Music metadata is the invisible layer of information attached to every track you distribute. It determines who gets paid, how your music is categorized, and whether Spotify and Apple Music can serve it to the right listeners. Most independent artists get metadata wrong and never notice — until they check their royalty statements and find streams that aren't paying. Or until their track appears under the wrong artist name. Or until Spotify's algorithm miscategorizes their music and sends it to the wrong listeners. This guide covers what you need to get right before you distribute.
The essential metadata fields (and common mistakes)
Track title: use exactly the same spelling and capitalization you want on Spotify, Apple Music, and Tidal. Inconsistent title formats across platforms create duplicate entries and split your stream count.
Artist name: must match exactly across all platforms. 'The Artist' and 'Artist, The' are treated as different artists. Decide on your format and apply it consistently from your very first release — changing it later is a lengthy support process.
ISRC code: International Standard Recording Code — a unique identifier for each recording. Your distributor (DistroKid, LANDR, TuneCore) generates this. Keep a record of every ISRC you're issued — you'll need them for sync licensing, publishing registration, and YouTube Content ID.
ISWC code: International Standard Musical Work Code — identifies the composition (different from the recording). Your publishing administrator (Songtrust, TuneCore Publishing, DistroKid Publishing) registers this. Needed to collect performance and sync royalties.
Genre metadata — why it matters for the algorithm
Spotify and Apple Music use genre tags from your distributor to initially categorize your music and determine which editorial playlists and algorithmic recommendations it's eligible for. If your music is tagged as 'pop' but sounds like 'R&B', you'll appear in the wrong playlist recommendations.
Most distributors allow primary and secondary genre tags. Be honest and specific: 'Neo-Soul' gets served to Neo-Soul listeners. 'R&B' is a massive category with lots of competition. The more specific your genre tag, the more efficiently the algorithm finds your exact audience.
Credits and songwriting metadata
Songwriter splits: register with a Performing Rights Organization (ASCAP, BMI, SESAC in the US; PRS in the UK; SOCAN in Canada). Unregistered songwriters don't collect performance royalties. This is money left on the table for every stream, sync, and radio play.
Producer credits: add producer credits in your distributor dashboard. Spotify's Loud & Clear report shows that producer royalty transparency is improving — make sure your producer is credited correctly so they get paid from any future streaming royalty changes.
Language and explicit content tags
Explicit content: always tag correctly. If your track has explicit lyrics and you mark it 'clean', Apple Music will flag it and you'll lose placements in family-friendly playlists. If you mark a clean track as 'explicit', you'll be excluded from those placements unnecessarily.
Language: flag the primary language of your track's lyrics. Spotify uses language metadata to serve tracks to relevant markets. A French rap track tagged in English won't get routed to French-speaking listeners as efficiently.

Can I fix metadata after I've already distributed?
Yes, but it's a process. Contact your distributor, request a metadata update, and it typically takes 1–2 weeks to propagate across all platforms. Some fields (like ISRC) cannot be changed without creating a new distribution entry.
Does metadata affect Spotify's algorithm directly?
Yes — genre tags, language, explicit flag, and mood tags all influence which playlists and recommendation algorithms your track is eligible for. Incorrect metadata is like mailing a letter with the wrong address.
Do I need to register with a PRO before distributing?
You should register with a PRO before your release goes live. Unregistered songs still earn streaming royalties via your distributor, but performance royalties (radio, live performance, sync plays) are lost without PRO registration. Join ASCAP, BMI, or your country's equivalent before your first release.
