Credits.fm

Credits.fm is an open index of music identifiers. Ask who wrote a song, who publishes it, who played and produced it, or what its codes are, and get answers from the Credits.fm index instead of a guess.

What it does:

• Finds a song by title and artist, or by any code: ISRC (recording), ISWC (musical work), IPI (songwriter or publisher), ISNI (creative contributor) or UPC (release).
• Returns songwriter credits with roles and publisher chains, performer and producer credits, and the links between a recording, its work, its writers and its releases.
• Lists the publishers a songwriter has worked with, from their IPI.
• Shows how each connection is sourced, and whether two independent sources agree.

Who it is for: songwriters, artists, managers, publishers, labels, researchers and anyone checking music credits.

Sources: The MLC (Mechanical Licensing Collective), CISAC, MusicBrainz and ISNI.org. Data is licensed CC-BY 4.0; please credit Credits.fm. Apple Music and Spotify supply supplementary titles and artist names only where the open sources have none.

Limits: read-only lookups of published industry data. It does not show streaming counts or royalties, and it does not hold contact details for anyone. A code missing from the index is a coverage gap; it says so rather than inventing one. No account or API key is needed.
