How to Run a Music Rights Audit Before Releasing Your Back Catalogue
An old master can be ready for streaming while its paperwork is nowhere to be found. If you’re preparing a reissue, a music rights audit helps you identify what you control, what needs permission, and what should stay off the release schedule.
The work starts with each recording, not the album as a whole. One disputed sample or unsigned co-writer agreement can affect a single track without stopping the rest of your catalogue.
Define the release before checking the rights
Write down what you plan to release: the original album, previously unreleased tracks, alternate mixes, remasters, or a selection across several projects. Include the intended countries, platforms, formats, release date, and whether you want to offer the music for sync licensing later.
That scope matters because an old permission may cover a physical release in one territory but say nothing about a worldwide digital reissue. A remix can also involve people and material absent from the original master.
Treat the release plan as a question for each agreement: does this document authorize this version, in these places, for this use? If the answer depends on an assumption, mark the track for further review. Streaming adds its own licensing and payment questions, as the legal analysis in Music Modernization and the Labyrinth of Streaming illustrates.
Build a track-by-track music rights audit
Give every proposed recording its own row in a spreadsheet or rights database. Don’t use one row for an album and assume its tracks share the same writers, samples, or contracts.

Separate the song from the recording
The composition is the underlying music and lyrics. The master is a particular recorded performance. A songwriter or publisher may control the first, while an artist or label controls the second. Owning a tape, paying for a session, or appearing in the credits doesn’t settle either question by itself.
For each track, identify the writers and publishers, then identify the master owner and any company administering the recording. Record performers and producers separately. Their contracts may create payment, consent, or credit obligations without making them composition owners.
Record claims and supporting evidence
A compact inventory can hold the essentials:
| Track record | Information to capture |
|---|---|
| Recording | Title, version, duration, release history, master claimant, and ISRC |
| Composition | Writer shares, publisher or administrator, work registration, and ISWC if assigned |
| Contributors | Featured artists, producers, session players, and relevant agreements |
| Third-party material | Samples, interpolations, beats, borrowed audio, and clearance documents |
| Limits and status | Territory, term, permitted uses, open questions, and evidence location |
An ISRC identifies a recording; an ISWC identifies a musical work. Neither number proves ownership. Attach a document reference to every significant claim, such as a signed agreement, registration record, statement, or dated correspondence.
Trace the agreements behind each claim
Credits tell you whom to contact, but contracts tell you what they agreed. Work back through recording deals, publishing agreements, assignments, licenses, producer terms, and distributor paperwork. Keep the signed version and any amendments together.
Find missing links in the chain
A label may have released an album under a license rather than owning its masters. An artist’s deal might cover named recordings but exclude later remixes. Check the parties, signature dates, covered assets, granted rights, territory, term, and any renewal provisions.
For an estate, establish who has authority to act for the relevant rights holder. For a catalogue that changed hands, collect the documents connecting the original owner to the current claimant. Don’t treat a distributor account or streaming listing as a substitute for that chain of title. The Copyright Office’s music marketplace report describes why music rights can be divided among multiple parties and arrangements.
Resolve co-writer shares on paper
Compare split sheets, publisher registrations, liner notes, and royalty statements. If two sources give different percentages, record both claims rather than choosing the one that makes the total reach 100%.
Contact the writers or their authorized representatives for a signed correction. A producer credit alone doesn’t establish a writing share, but an undocumented contribution can’t simply be ignored. Record the basis for the final split and who approved it.
Check samples, beats, and other borrowed material
Legacy sessions can hide third-party material in the mix. Listen to the final master and review session files, track sheets, producer notes, and earlier release credits where available.
Identify what entered the recording
Log copied audio, replayed phrases, borrowed lyrics, leased beats, and archival speech. Include the source, where it appears, and the person who introduced it. A replayed passage may avoid copying the original master while still raising a composition clearance question.
For a sampled recording, clearance usually involves both the source master and its underlying composition. A short excerpt or an old release date doesn’t establish permission. Neither does a producer’s statement that the sample was “cleared” unless you can find the authorization.
Match each license to the new use
Read the actual permission for named tracks, approved versions, countries, formats, duration, and payment conditions. A license granted for a previous release may be limited by territory or may have expired.
If permission is missing, seek it before delivery. Otherwise, consider removing or replacing the material, then document the revised master. Don’t mark a track cleared while negotiations remain open.
Reconcile recordings and metadata
Back-catalogue data often comes from several sources: vinyl sleeves, CD booklets, collection-society records, old distributor deliveries, and current platform listings. They may disagree because a track was retitled, a mix was replaced, or a writer’s name was entered differently.

Match every identifier to the right version
Compare the audio, duration, mix name, performer credits, release date, and existing ISRC before preparing a new delivery. Keep original and alternate recordings distinct in the inventory. Verify whether an existing identifier belongs to the audio you’re submitting rather than copying it from an album-level file.
Then compare composition titles, writers, and publishers with available work registrations. A cover, live take, and studio recording can share a composition while using different masters. The recording-to-work connection matters: congressional testimony on unmatched recordings explains how missing matches can prevent publishers and songwriters from receiving mechanical royalties.
Correct discrepancies before delivery
Save screenshots or exports of conflicting entries, then determine which source has authority for the fact in question. A sleeve may help establish historical credits; a signed split agreement is stronger evidence of agreed shares.
Send corrections to the appropriate distributor, label, publisher, or registration administrator. Keep confirmation of what changed. Digital-service usage reports and licensing data have their own reporting rules, described in the Music Modernization Act rulemaking. Accurate delivery data helps, but it doesn’t cure a disputed ownership claim.
Put unresolved rights in a separate queue
A music rights audit should distinguish a missing document from a known dispute. Both need attention, but they call for different next steps.
Preserve the evidence trail
Create a folder for each track with contracts, amendments, split sheets, sample licenses, registrations, statements, correspondence, and release files. Name documents clearly and keep dated versions. In the inventory, note which document supports each claim and what remains unverified.
Record conversations as dated notes, then request written confirmation of any agreement reached. If an old contract has disappeared, supporting emails and payment records may help reconstruct the history. They don’t automatically replace a signed grant.
Refer contested ownership for legal review
If two parties claim the same master or disagree about a writer share, pause that track and consult an entertainment lawyer familiar with the relevant countries. The same applies when you can’t establish whether a sample was licensed or whether a grant still applies.
Older U.S. agreements can raise termination questions. For certain grants made from January 1, 1978, onward, 17 U.S.C. §203 allows termination after 35 years, subject to formal notice requirements; works made for hire are excluded from that provision. These rules aren’t a shortcut to declaring rights reverted. Ask counsel to review the grant and dates.
Make the release decision track by track
Assign each master a status: ready, ready after a named correction, awaiting permission, or held for legal review. Require the supporting files to be present before changing a status to ready. This lets a clear track move ahead without burying an unresolved one inside an album delivery.
Before upload, compare the final audio files and metadata with the approved inventory. Confirm that credits, ownership claims, licenses, and territorial settings reflect what you can document. Keep a copy of the delivered files and the distributor’s confirmation.
Public access isn’t proof of reuse rights. If you share recordings as Free Music, keep the terms of that access alongside the catalogue records. A listener’s ability to stream a track doesn’t grant another party permission to sample or redistribute it.
Key Takeaways
- Audit each recording separately, even when several tracks appeared on the same original release.
- Check composition and master ownership against documents, not platform credits alone.
- Flag unsigned splits, missing agreements, borrowed material, and licenses with narrow terms.
- Preserve the evidence behind each decision, and hold disputed tracks for legal review.
Frequently Asked Questions
Can I re-release a master because I possess the original tape?
Possession of the tape doesn’t establish copyright ownership or a right to distribute the recording. Review the recording agreement and any later transfers. Also check the composition and third-party material in the track.
Does an old sample clearance cover a new digital release?
Only if its terms cover the proposed version and use. Check the named recording, territories, formats, term, and any conditions. If the agreement can’t be located or its scope is disputed, seek professional advice before releasing the track.
Should I assign a new ISRC to every reissue?
Don’t assign identifiers by guesswork. First establish which recording each existing ISRC identifies and whether the reissue uses that same audio or a different version. Confirm the appropriate treatment with your identifier manager or distributor before delivery.
What if a co-writer won’t confirm their share?
Keep the competing evidence and correspondence in the track file. Don’t present an estimated split as agreed fact. Hold the affected work for resolution, and involve an entertainment lawyer if ownership remains contested.
Conclusion
A back-catalogue release is only as clear as its least-documented track. Track-level evidence lets you separate recordings you can deliver from those that need a signature, a correction, or legal advice.
Start with the proposed audio and work backward through its rights. When the paperwork matches the release, you can put the music back into circulation with a defensible record of why.
