Catalog
Every song that a writer or publisher owns or administers. When someone says "your catalog," they mean all compositions you've written, whether registered or not.
Chain of Title
A written record tracing each song share from the original writers through later assignments, transfers, or estate inheritances. Before paying anybody, a licensor checks that this ownership history is clean.
CISAC
The International Confederation of Societies of Authors and Composers — a worldwide umbrella organization linking performing rights societies so reciprocal agreements can recognize one another's registrations.
Clearance
Securing legal permission before music airs in a sample, cover, or sync placement. Without clearance, that use can become the basis for an infringement claim.
CMO (Collective Management Organization)
A broad name for a society collecting and distributing royalties for many rights holders together — including PROs, mechanical societies, and neighboring-rights bodies. Through reciprocal society agreements, your works can be collected across 240+ countries and territories worldwide.
Full CMO directory→Co-Administration
Two or more publishers or admins representing separate shares in one song — often because its co-writers signed with different publishing companies. Each one manages only the share belonging to its writer.
Co-Publishing Deal
The writer retains their writer's share while sharing ownership of the publisher's share with a publishing company, typically receiving an advance and the company's promotional support in return.
Co-Writer
Someone whose original contribution to a song includes lyrics, melody, or both, giving them ownership of a composition share. Correct payment requires registering every co-writer and their individual share.
Composer
Whoever creates a song's music — its melody, harmony, and arrangement. For a song with words, one credited writer may be both composer and lyricist, or two people may fill those roles.
Composition
The underlying song — melody, lyrics, and structure — rather than any one recording. Dozens of recordings (covers, remixes, samples) can all rest on a single composition copyright.
Compulsory License
Under this US legal mechanism, anyone may record and release a cover once a song is already released, without seeking permission, provided they pay the statutory mechanical rate. That's what makes covers legal without negotiating directly with the original writer.
Content ID
YouTube's automatic tool that compares uploaded videos with its database of registered recordings and compositions. When a Content ID claim is correct, ad revenue reaches the rights holder; if the match goes unclaimed, the revenue goes nowhere.
Controlled Composition Clause
Some recording contracts use this clause to limit what the record label pays in mechanical royalties for the artist's own songs, often setting the cap below the statutory rate. Read it carefully before you sign a label deal.
Copyright
Legal protection for an original creative work — in music, the composition and sound recording each receive a distinct copyright as soon as they're fixed in recorded or written form.
Copyright Office
The US federal agency within the Library of Congress that formally registers a composition or recording, creating a public authorship record. This process is separate from — and unnecessary for — registration with a PRO, the MLC, or a publishing administrator.
Copyright Term
The period before copyright expires and a work moves into the public domain. In the US, it generally runs through the last surviving author's life, plus 70 years.
Cover Song
A performer other than the original artist makes a new recording of an already released composition. Its composition royalties continue going to the original writers; the cover artist owns only the master royalties from the new recording.
Cue Sheet
A time-coded record listing all music in a film, TV episode, or show — its writer, performer, and duration. PROs rely on cue sheets to work out performance royalties from sync placements.
CWR (Common Works Registration)
A standard electronic format publishers send to PROs for work registration — it packages song titles, writers, splits, and IDs into one structured batch, avoiding manual portal entry for every song.
