Music Release Metadata Checklist for UK Independent Artists

One misplaced full stop can send a release to the wrong artist page or leave a songwriter out of the credits. Good music release metadata keeps your single, EP, or album connected to the right people, rights, artwork, and streaming profiles.

The music may be finished, but distribution is not a copy-and-paste job. Treat the information around your tracks with the same care as the master itself, because platforms and royalty systems rely on it.

Use this checklist before you submit anything to your distributor.

Music Release Metadata Starts With One Master Record

Build a single release sheet before logging into your distributor. It stops different spellings, dates, and codes appearing across messages, artwork folders, registration forms, and upload pages.

The Musicians’ Union lists artist and release titles, writers, label details, copyright information, and identifiers among the data artists may need when distributing work. Its guide to releasing music products is a useful UK reference point.

Keep a release sheet for every project

Create a spreadsheet or shared document with one tab for the release and one for each track. Give your manager, producer, or label partner read-only access once you have checked it.

Include:

• Release title, format, catalogue number, planned date, territories, and label name.
• Main artist name, track titles, versions, featured artists, and track order.
• ISRCs for recordings and a UPC or EAN for the release package.
• Writer, producer, performer, mixer, engineer, and publisher information.
• Copyright lines, artwork ownership, lyric status, explicit flags, and final audio filenames.

A clear master record turns corrections into a five-minute job rather than a hunt through old emails.

Match every field exactly

Choose the approved spelling once, then use it everywhere. That includes accents, apostrophes, capital letters, spaces, and initials.

For example, “Mark Leigh” and “MarkLeigh” are different names to a database. The same rule applies to “Don’t Look Back”, “Dont Look Back”, and “Don’t Look Back (Radio Edit)”. Small changes can create duplicate listings or confuse search results.

Your release sheet is the source of truth. Update it first, then copy its details into distributor and royalty-registration forms.

Use One Artist Name Across Every Platform

Your public artist name is more than branding. It is the label attached to searches, playlists, credits, analytics, royalty records, and your existing catalogue.

Before upload, search Spotify, Apple Music, Amazon Music, Deezer, and TIDAL for similar names. A shared name does not stop you releasing music, but it makes accurate profile matching more important.

Set the main artist and featured artist roles correctly

Put the lead act in the main artist field. Add guest vocalists and collaborators through your distributor’s featured artist or primary artist options, based on their actual role.

Do not type “feat. Alex Stone” into a main artist field unless the form tells you to. Instead, use the track-title format your distributor requires and add Alex Stone as a featured artist in the contributor area.

You can check how consistent presentation looks on Mark Leigh’s Spotify artist profile. Keep the same artist identity on every release, even if you change your visual style.

Write version titles that describe the audio

A version title tells listeners and platforms what is different about a recording. Use a version label only when it is true.

Useful examples include:

• “Northern Lights (Acoustic Version)”
• “Northern Lights (Radio Edit)”
• “Northern Lights (Live at The Garage)”
• “Northern Lights (2026 Remaster)”

Do not add “new”, “official”, “exclusive”, chart claims, or promotional copy to track titles. Platforms may reject it, and it makes the catalogue look untidy later.

Assign ISRCs, UPCs, and Catalogue Numbers Properly

Identifiers can look like admin, yet they connect recordings to reporting and payment systems. Keep them organised from the first upload.

An ISRC identifies one sound recording. A UPC or EAN identifies the release package, whether that package is a one-track single or a 12-track album.

Give each recording its own ISRC

One finished recording needs one ISRC. Keep that code attached to the exact audio master, title, main artist, version title, duration, and first publication year in your release sheet.

Your distributor may generate ISRCs, or you may supply codes from your own allocation. Either route is fine if you log them carefully. Do not assign the same ISRC to a different recording because the title is similar.

A new recording, a materially changed remaster, or a new live performance may need its own identifier. Check the current rules before assigning a code.

Separate release-level and track-level identifiers

Use the UPC or EAN for the overall product. Use ISRCs for individual recordings within it. Do not swap them or use a UPC as a track identifier.

You may also use an internal catalogue number, such as ML-2026-014. That number helps you organise files, invoices, artwork, and physical stock. It does not replace an ISRC or UPC.

Accurate music release metadata also makes it easier to trace a release months later, when a platform report or royalty statement uses an unfamiliar code.

Credit Every Contributor Before Distribution

Credits affect recognition, relationships, royalty administration, and the public story of a record. Leaving them until release week is how names get missed.

Ask every contributor to confirm their preferred credit spelling before you submit. Do not rely on old social profiles or a memory from a late-night session.

Record creative and technical credits

Collect the legal names needed for agreements and royalty registrations, alongside the public names that appear in platform credits. Depending on the track, record songwriters, composers, lyricists, producers, featured performers, session musicians, mixers, mastering engineers, and publishers.

If a producer wants “J. North” in public credits but contracts under Jamie North, record both correctly in your files. The public credit and legal paperwork have different jobs.

Check split agreements before release. A friendly verbal agreement is not enough when the track starts earning money or gains attention.

Confirm who owns what

The sound recording is usually covered by the (P) line. The musical composition and lyrics are covered by the (C) line. The owner may be the same person, but do not assume that.

For example, a band may own the master recording while two writers share the composition. A producer may also have a contractual royalty or master-rights interest. Get permission for samples, beats, photographs, designs, and featured performances before delivery.

Keep signed agreements, licences, invoices, and artwork permissions in the release folder. If a dispute arises, those records matter more than an Instagram message.

Label Explicit Content and Prepare Platform-Ready Artwork

Explicit-content labelling needs an honest decision at upload. Mark a track explicit when it contains strong language, sexual content, or other material that meets your distributor’s policy.

Do not mark a clean song explicit for attention. Equally, do not avoid the label because you worry it will reduce plays. Incorrect flags can lead to corrections, complaints, or delayed delivery.

Review lyrics and audio, not the title alone

A title can sound provocative without needing an explicit tag. Meanwhile, a harmless-looking title may contain language that requires one.

Listen through the final master while reading the approved lyric sheet. Check every version too. A clean edit should not carry the explicit flag if the restricted words and content have been removed.

If you release a track with adult content, keep the artwork and metadata treatment consistent with the status you submit.

Use artwork that passes store checks

Create a square cover at high resolution. Apple Music currently requires album artwork to be a perfect square and supports artwork at 4,000 by 4,000 pixels or larger. A 4,000 by 4,000 pixel JPEG is a practical delivery file for most distributors.

Avoid URLs, social handles, QR codes, price claims, release dates, retailer logos, barcodes, unauthorised photographs, and misleading text. Do not use a generic parental-advisory image on a release that is not marked explicit.

If you use generative AI in artwork, check your distributor’s current disclosure rules. You still need the right to use the image. A generated file does not automatically give you safe artwork rights.

You can also compare how finished covers sit beside a release on Mark Leigh’s Apple Music page.

Set the Date Early and Respect Distributor Deadlines

A Friday release can arrive on time and still miss promotional opportunities. Distributor processing, store delivery, profile matching, and playlist pitching all take time.

Upload early enough to fix rejected art, incorrect credits, or a misplaced explicit flag without changing your planned date.

Work backwards from release day

For a normal digital release, submit to your distributor at least three to four weeks ahead. Some distributors can deliver faster, but fast delivery leaves no room for problems.

Spotify’s editorial pitching process needs the unreleased song to appear in Spotify for Artists first. The usual minimum pitch window is seven days before release. Therefore, a Wednesday upload for a Friday release is already too late for a proper campaign.

Set a private internal deadline before the distributor deadline. At that point, lock the audio master, metadata sheet, credits, artwork, and rights documents.

Check territory and pre-order settings

Choose where the music can be sold or streamed. Global distribution is common, but you may need to exclude territories where rights, samples, or contracts limit you.

Also confirm whether you want pre-save support, pre-orders, instant-gratification tracks, or a future release date. These settings vary by distributor and platform, so verify the current specifications before submitting.

Run This Final Pre-Submission Check

Open your release sheet beside the distributor upload form. Read every field out loud before you press submit, especially after copying data from an older release.

Check these points:

• The artist name, release title, track titles, and version labels match the approved sheet.
• Every featured artist, writer, producer, and technical contributor is credited in the right role.
• Each track has the correct ISRC, while the release has its own UPC or EAN.
• The (P) and (C) lines name the correct rights holders and use the correct year.
• Audio files are final, correctly sequenced, and match the listed versions.
• Artwork is square, high-resolution, original, and free of prohibited promotional text.
• Explicit flags match the finished lyrics and audio.
• The release date leaves enough time for delivery, pitching, and corrections.

If you are also placing a release on video platforms, keep the title, artwork, and artist identity consistent there as well. Free Music releases and music videos still need clear naming and accurate credits for viewers to find the correct work.

A Clean Metadata Record Protects the Release

Strong songs deserve clean listings, correct credits, and royalty data that points to the right people. The best music release metadata is accurate before it reaches a distributor, not patched after fans have already found the track.

Give every name, code, credit, rights line, and image one final check. That discipline protects your catalogue and lets listeners focus on the music.
