Music Metadata and Release Data Management
Metadata is the information attached to your release that platforms, PROs, and royalty systems actually use to identify, categorize, and pay out your music correctly. Getting it wrong is one of the most common — and most avoidable — reasons artists lose money or visibility.
What Counts as Metadata
- Basic info: song title, artist name, featured artists, album/EP name, release date, genre, and language.
- Identifier codes: an ISRC (identifies the specific recording), an ISWC (identifies the underlying composition), and a UPC/EAN (identifies the release as a product).
- Contributor credits: songwriters, producers, performers, and their specific roles — this is what determines who gets paid what.
- Rights info: the ℗ line (recording copyright) and © line (composition copyright), and explicit content flags.
ISRC
- What it identifies
- This specific recording — a unique code, permanently tied to this exact master.
- Where it comes from
- Usually assigned automatically by your distributor when you upload, though you can register your own ISRC prefix if you distribute frequently.
ISWC
- What it identifies
- The underlying song itself — separate from any specific recording of it.
- Where it comes from
- Assigned when you register the composition with your PRO — another reason to register songs promptly.
UPC / EAN
- What it identifies
- The release as a whole — the single, EP, or album, as a distributable product.
- Where it comes from
- Typically assigned automatically by your distributor at the release level.
What Bad Metadata Actually Costs You
- Royalty misattribution. If contributor splits or credits are entered incorrectly, royalties can be paid to the wrong person or go uncollected entirely.
- Broken discovery. Wrong or missing genre and mood tags make it harder for algorithmic playlists and search to correctly categorize your music.
- Rejected or delayed releases. Distributors reject uploads with inconsistent or incomplete metadata, which can push back your release date at the worst possible time.
- Mismatched records across systems. If your distributor, PRO, and MLC have different spellings of your name or song title, it becomes much harder for royalties to match up automatically — see the PRO & Royalty Checklist for why this specifically trips people up.
- Sync licensing friction. Supervisors and licensing platforms rely on clean metadata to quickly evaluate and clear a track — messy metadata can quietly take you out of consideration.
Keeping Your Catalog's Metadata Clean
Use one consistent artist name, always
Exact spelling, capitalization, and formatting — every time, everywhere. Inconsistency here is the single most common metadata problem.
Keep a simple release tracker
A spreadsheet with every release's title, ISRC, ISWC, UPC, and contributor splits is enough — it turns "what were the exact credits on that song" from a scramble into a lookup.
Double-check before you submit
Review title formatting (avoid inconsistent "feat." styles), genre accuracy, and contributor spelling before your distributor upload — some fields are difficult or impossible to change after release.
Keep your systems in sync
When you register with a PRO, the MLC, or a publishing administrator, make sure the title and contributor details exactly match what's on your distributor — mismatches are what cause royalties to go uncollected.
