Music Metadata Explained: Get It Right the First Time

Metadata is the information attached to your release — the names, credits and codes that tell stores and streaming services what your music is and who made it. Get it right and your music is discoverable and pays you correctly. Get it wrong and releases get rejected, royalties go missing, and your profile gets messy.

Why metadata matters so much

Metadata drives three things: discovery (how listeners and algorithms find you), royalties (making sure every stream pays the right people), and identity (keeping all your songs under one verified profile). It's not paperwork — it's your career's plumbing.

The key fields

• Artist name — spelled and capitalised identically on every release, forever.
• Track & release title — no promo text like "(Official Video)" or "prod. by".
• Featured artists — credited in the feature field, not typed into the title.
• Songwriters & producers — real legal names, so publishing royalties reach them.
• ISRC and UPC codes — the unique IDs for your track and release. Learn the difference in our ISRC vs UPC guide. Mazufa provides both free.
• Genre, language and explicit flag — accurate tags help the right listeners find you.

Common mistakes that get releases rejected

Inconsistent artist names (which split your streams across duplicate profiles), features typed into the title, ALL-CAPS or emoji in titles, missing songwriter credits, and low-resolution or text-covered artwork. Any of these can delay or block your release.

Best practice: decide once, repeat forever

Write down exactly how your artist name, and your usual collaborators' names, should appear — then use that every single time. Consistency is what keeps everything under one clean, verified profile.
