Credits, completely

44 · 2026-09-12 · 19 min read · Español

A credit is a name attached to a role on a song, a recording or a release, delivered as metadata with the music and displayed by the stores as it was sent. There are three kinds because a release carries three nested things — the song, the recording of it, and the package the recording ships in — and each kind has a different reader after delivery: one places the release, one is displayed, and one is handed on to the people who pay writers. No kind transfers ownership, creates a share or pays anyone by itself. Every piece on this site that argues about a credit starts one step after this page.

• A credit is a name attached to a role, delivered with the music. Spotify shows all credits from the metadata a label or distributor sends, and Apple’s specification treats any contributor, performing or not, as an artist with a role.
• There are three kinds: display-artist credits, main or primary and featured, on the release and the recording; contributor credits, performers, producers and engineers, on the recording; and writer credits, Composer, Lyricist and Songwriter, on the song.
• Each kind has a different reader. Primary status decides which artist page a release appears on; contributor credits are displayed; writer credits are passed on, and Apple warns that missing songwriter metadata may delay royalties to publishers and songwriters.
• Credits are entered on each track, and a credit that holds across every track is entered again at release level. Both stores read the role, never the title.
• No credit transfers ownership, creates a share or pays anyone by itself. Ownership of a recording moves by a signed writing, and a share by an agreement.

What is a credit, exactly?

A credit is a name attached to a role on a song, a recording or a release, delivered as metadata and shown as sent.

Start with the stores, because they are the ones showing it. Spotify’s page on credits opens with the whole mechanism in one sentence: “We show all credits from the metadata your label or distributor sends us, from producers and engineers to songwriters and featured artists.” Apple’s delivery specification is broader still about who counts. In the artist block, “artist” may be “any contributor including non-performing persons (for example, producer), groups (for example, a band name), or composition-related contributors (for example, songwriter/lyricist, or composer).” A name, a role, and a flag saying whether the name is primary. Every credits panel you have ever scrolled is a rendering of that.

Which means a credit is a record before it is an honour. It is not adjudicated, weighed or checked against what happened in the room; it is typed, delivered and displayed. Spotify’s metadata guidelines say so in plain words — “We display your music exactly as it’s delivered to us” — and add where the typing happens: “Your metadata is set by your label or distributor before they deliver your music to us.”

The standard the delivery travels in goes one step further and admits that the record and the room can differ. DDEX’s release message carries a flag, IsCredited, for a contribution that is real and not credited, and DDEX’s own worked example is Billy Preston, who played electric piano at the Beatles’ rooftop concert and, in DDEX’s words, “was not officially credited for this performance.” Half a century later a standards body wrote him a checkbox.

Why does one release carry three different credit lists?

Because a release holds three nested things, the song, the recording of it and the package itself, and each carries its own names and roles.

DDEX, the standards body whose message your distributor’s delivery is written in, states the structure on a page with the question in its title: “Music products are made of several nested creations: A musical work (the composition and lyrics of a song); A resource (the sound recording or video that an artist has created by performing and recording a Musical Work); and A release that groups resources into a single tradable collection.” Then the consequence: “Releases, resources and musical works all have their own titles and artist information.” Three things, three lists, one box on the form.

The dictionary behind the standard splits the roles the same way. A ContributorRole, “A Role played by a Contributor,” has three children: ArtistRole, “A Role played by an Artist”; ResourceContributorRole, “A Role played by a Contributor to a Resource”; and WorkContributorRole, “A Role played by a Contributor to a Work.” Three kinds of credit, in the standard’s own words.

The distinction that does the most work is the first one, between a display artist and a contributor, and DDEX explains it with a record everybody knows. “Cruel Summer” was released under Taylor Swift’s name, so she is its display artist, whereas Jack Antonoff, Michael Riddleberger and Serban Ghenea “are just ‘contributors’; they contributed to the recording as co-producer, drummer and mixing engineer, respectively, but the recording is not marketed under their names.” Then the sentence that untangles most credit arguments: “However, the main artist is usually also a contributor.” Swift is the display artist and, on the same recording, the lead vocalist, a writer and a co-producer. One person, two lists, three roles.

The third list is where the writers go, and DDEX is exact about why it is separate. Direct contributors are “individuals that were in the studio when the recording or mixing took place.” “Composers and arrangers are, however, no direct contributor roles. If an individual has contributed to writing the song, that person should be communicated as an indirect contributor.” The writer’s credit sits on the song, underneath the recording. Apple’s specification asks for the same three, plus the guest: Performer roles, Composition and Lyrics roles, and Production and Engineering roles, each “Required for albums and tracks,” and Featuring or With, “Required if there is a featured artist on the album or track.” What each field on that form is, and which of them can ever be changed, is the field map’s subject. This page is about the kinds.

Which credits decide where a release lands?

The display-artist credits: whoever is marked primary or main artist gets the release on their page, and a featured artist gets it on theirs.

Apple’s specification defines primary status by its effect and nothing else: “The primary role indicates whether the album appears on the artist’s page on Apple Music. Typically, there are one or two primary (lead) artists and several supporting artists. The primary role is reserved for the primary (lead) artists.” And: “Only primary artists are displayed with the album.” The featured role is defined the same way — adding an artist with the Featuring or With role “ensures that the album will show up on the featured artist’s page.” Spotify’s guidelines say it from the artist’s side: “Roles dictate which artists are credited on your song or release, and how the music appears on their Spotify artist profile.”

So the primary flag is not a compliment. It is an instruction to a matcher, and how the matcher places a release is its own piece. What the flag may hold is short: the main performing artists, credited as main artist on all content in Spotify’s style guide and listed as Primary at album and track level in Apple’s; and a guest, in the Featuring or With role, who “must not be marked Primary.” What that guest role buys and costs is the featured-artist piece’s whole subject. DDEX’s two living display roles are the same pair under different names: MainArtist, “the primary artist(s) under whose name a release, sound recording or video has been released,” and FeaturedArtist, prominently featured and not the main artist.

Three edges of the field, each one clause and a link. No more than four main artists at product level, Various Artists from five, and companies and labels are not artists; every name in its own field, spelled the one way; and a featured name typed into a title instead of the field is a rejection, not a style. A remixer is the third display role, and the FAQ takes it.

What does a contributor credit do?

It records who did what on the recording, an instrument, a production role or an engineering role, and the stores display it.

Apple’s style guide, section 2.14, wants the instrument. Performing artists “must be credited accurately at the track level with their specific instruments and/or roles,” and “must not be given the Primary or Featured/With roles at either the album or track level unless they are also Primary or Featured/With artists on the recording.” The specification closes the loophole everybody uses: “Generic roles (such as performer, artist, contributor) are not considered as a performer role.” A performer credit is a name and an instrument. Without the instrument it is a name on a list.

Apple’s own example is Rubber Soul. At album level George Martin is credited as Producer and as Mixing Engineer; at track level, on “In My Life,” he is credited again, as Piano. Norman Smith is Studio Engineer and Mixing Engineer. Each Beatle is listed with what he played and sang. Not one of them is primary — the Beatles are — and the guide says “There is no need to credit a band as a performer when the specific performers or band members are known.” Spotify’s style guide asks for the same thing in DDEX terms: “always list the instrument as user defined artist role for all artists, in addition to the main and featured artist roles.”

The production and engineering roles on the same list are contributor credits too. Apple’s recommended list runs Producer, Co-Producer, Recording Engineer, Mixing Engineer, Mastering Engineer, Assistant Engineer, Editing Engineer and Immersive Mixing Engineer. What the producer words mean, and which of them is a claim on anything, is its own piece; who is paid among the engineers is a piece not yet written. DDEX adds one refinement: the credited string can differ from the role. Its example is a violinist delivered as Violin with a display credit of “Johnny on the fiddle.” The panel shows the fiddle; the record holds the violin.

One money sentence, because the class is the credit’s and the numbers are not. In the United States, 17 U.S.C. § 114(g)(2) pays featured recording artists and nonfeatured musicians and vocalists from different shares of one statutory royalty, and in Canada section 19 of the Copyright Act divides equitable remuneration equally between performers and makers. Which class each credit puts a performer in, and what each share is, is the featured-and-side-artist piece’s, and a session player’s paper is the assignment’s. Nothing on this page states a percentage.

Now the reason that is not the royalty. Ten years from now somebody is going to need to know who the fuck played bass on track four, and the credits are the only place anybody will look.

Which credits belong to the song, and who reads them?

The writing credits, Composer, Lyricist and Songwriter, attach to the song, and a society pays on a registration of that song, not on a credit.

Apple’s guide, section 2.15, sets the three words: “When the breakdown of contributions to a work is known, use the Composer role to credit the creator of the music composition, and the Lyrics role to credit anyone who contributed to drafting lyrics of a song. If a contributor was involved in both composition and lyrics, or if their specific contribution to the work isn’t known, use the Songwriter role.” A folk song or a chant takes Anonymous or Traditional. DDEX’s writer roles are the same three plus one for the case where a writer is known to have contributed and nobody recorded how: Lyricist, Composer, ComposerLyricist and ComposerAndOrLyricist. Spotify’s guide keeps writers off the cover unless they also perform: “non-performing artists such as composers must not be listed as Main Artist or Featured Artist, unless they are also performers of the content.”

Who reads them. The store displays them — Spotify makes a songwriter credit clickable where the writer has a Songwriter Page, and says those pages are in beta. And the store passes them on. Apple’s specification carries one note under its role list, and it is the only sentence in either document that mentions money: “Failure to add full and accurate songwriter metadata in a timely manner may delay payment of royalties to publishers and songwriters.” May delay. Not decide, not create, not pay. The Muses have carried a writing credit on every epic since Homer and have never once been paid.

What pays a writer is a registration, not a credit — with the collector that holds the stream in question — and what decides the size of it is the writer share, which is a split sheet’s whole life and none of this page. A credit is not a share: a song can carry the credit and no share, or the share and no credit. And a credit is not authorship either, though it is evidence of it — the courts weigh how the parties credited themselves as one sign of what they intended, and a name in a Songwriter field has never made anybody a co-author on its own. Which word goes on which contributor is a metadata question with its own piece to come.

What can a credit never do?

A credit cannot transfer ownership, create a share or pay anyone by itself; ownership moves by a signed writing and a share by an agreement.

The law is one sentence long. Under 17 U.S.C. § 204(a), a transfer of copyright ownership “is not valid unless an instrument of conveyance, or a note or memorandum of the transfer, is in writing and signed by the owner of the rights conveyed.” A credit is none of those things. It is a name on a role in a delivery, typed by whoever delivered. The player’s rights move by the assignment, the producer’s by the clause, and neither document is the credits panel. A credit is a plaque. Nobody has ever repossessed a building by unscrewing the plaque.

The same holds for money, in every kind. The producer piece states it for producers — points, a letter of direction and a signed transfer, every one a document that is not the credit list — and the featured piece states it for guests: a credit is not a contract. It holds for writers, above. The one exception the law makes is a class, not an amount: a performer’s credit class decides which statutory pool they are in, and the pool is paid by a collector on a registration, not by a store on a panel.

And it holds in reverse, which is where it costs money rather than pride. Refusing somebody a word does not undo an agreement already signed. Granting the word does not create one. Everything a credit gets asked to do — settle a share, record a fee, close an ownership question — is a job for a piece of paper that already has a name on this site, and the credit is where the paper’s answer gets displayed.

Do credits go on the track or on the release?

Both: every credit is entered on each track, and a credit that holds across every track is entered again at release level.

Spotify’s guidelines: roles “need to be set at both track-level and release-level.” Apple says when the second entry is owed. A featured artist who is “the same on every track” must also be listed at the album level. A writer who has written “all words or lyrics for all recordings on an album” is listed at both levels. A production role “credited consistently across all tracks” must also be credited at the album level. Spotify’s style guide has the same pair for guests — “Artists featured on every track on a product must also be listed as a featured artist at product level” — and a cap for the cover: no more than four main artists at product level, and Various Artists, which “must not be listed as a track-level artist,” from five.

The rule underneath the rules: the track is the truth and the release is the summary. A credit exists because somebody did something on a recording; the album-level copy is owed only when the same thing is true of every recording. Fill the tracks and the release follows. Fill the release and hope, and the tracks are empty, which is what the panel shows.

What happens to a credit after delivery?

The store displays it as delivered; a wrong or missing credit is corrected by the distributor redelivering the metadata, about seven days on Spotify.

Spotify’s page on fixing metadata lists what a distributor’s update can change, and two lines on it are this page’s subject, kept separate on Spotify’s own list: “Your role on the music (main artist, featured artist, or remixer)” and “Credits.” The next two sentences are the whole after-delivery story. “Your label or distributor needs to send a metadata update to us with the right info.” “We can’t change this manually on our end because we show music according to the metadata sent to us.” The credits page gives the route and the clock — “contact your label or distributor and ask them to resend the track’s metadata with the correct credits. After we receive the update, credits usually appear within 7 days” — and one caveat that decides more than it looks: “Some distributors don’t support credits yet.”

So a credit has one door in and one door out, and both are the distributor’s. What happens between a distributor and each store, and what to do when a name is missing on one service and present on another, are two pieces not yet written, and nothing here anticipates them. What Apple says about the credit you do not have yet is one rule, already on the field map: omit it, and never deliver a placeholder.

What to settle before the credits are typed

Settle the names, the display artists, every performer’s instrument, the writers and their shares, and the production words, before anyone opens the form.

• One spelling of every name. Five comparisons ride on it, and the credits inherit the one you choose.
• Who is primary, who is featured, who is a contributor. The guest role has a price and a discography consequence; decide it when you book the session.
• Every performer with an instrument. A name without one is not a performer credit at either store, and the player’s one-page assignment is signed before they leave.
• Every writer with a role, and the split sheet beside it. The credit says who; the sheet says how much; neither says the other.
• The production words, as they will appear. Producer, co-producer and executive producer are three claims, and the third is not about the recording.
• Everything a credit cannot do, on paper. A share, a fee, a percentage, an ownership question — each has its document, and the credit is where the document’s answer is displayed.

That covers the next release. For the catalogue behind it, the audit checklist’s metadata layer has a box for credits in the right categories, and this page is what “right” means.

FAQ

Is a songwriter credit the same as a writer share?

No. A songwriter credit is a name on a role in the delivery, and a writer share is a percentage on a split sheet and in a society’s registration. A song can carry the credit and no share, or the share and no credit, and only the share is paid on. What a split sheet is and where it sits is its own page.

Do I credit the band, or every member?

Every member, with the instrument each one played, at the track level. Apple’s specification says a band or group should not be collectively credited with multiple roles like Vocals, Guitar, Bass and Drums, and its style guide adds that there is no need to credit a band as a performer when the specific members are known. The band’s name is the primary artist; the members are its contributors.

Is a remixer a main artist?

No. Apple’s style guide lists the original artist as Primary with the remixer assigned the Remixer role, and Spotify’s says a remixed track must list the original artist at track level as main artist and the remixing artist as a remixer. Spotify’s own list of what a distributor’s update can change names “main artist, featured artist, or remixer” as one field, which is the field a wrong remix credit is fixed in.

Is a sampled artist a featured artist?

No. Apple’s style guide credits the artist a sample, a licensed verse or a licensed beat came from with the Sampled Artist, Licensed Verse or Licensed Beat role, and says not to credit them as Primary, With or Featuring; its own incorrect example is a sampled artist listed as Featuring. Whether the sample was cleared is a licensing question, and no credit answers it.

Keeping the register

Three kinds of credit, two levels, and a form that shows you one box. CatalogTracker keeps them the way the standard does: a party carries an artist role — Main Artist, Featured Artist, Guest Artist, from a vocabulary of seven — and, separately, contributor credits from a vocabulary of nineteen, each attached per track and per release, with a history of who changed what and what it said before. It will not decide who deserves a word. It will show you what you delivered, in the shape the delivery has. In development for iPhone.
