A composition is the underlying lyrics and melody of a song with ownership belonging to the songwriters, composer, lyricist and their publisher. A sound recording is the recorded performance of that composition referred to as the master and belonging to the performing artist or record label. Each is a separate work with its own owners and rights.

Once a song is written and recorded, its ownership, credits and identifiers should be documented separately for the composition and the master recording. On the publishing side, writers use split sheets to confirm composition shares, connect those shares to their IPI numbers, and ensure the work is registered with the appropriate PRO for performance royalties and with The MLC—directly or through a publisher or administrator—for U.S. digital mechanical royalties; an ISWC may be assigned separately through an authorized agency. On the master side, agreements document artist, producer and label ownership or royalty participation, while an ISRC identifies the specific recording and SoundExchange registration supports the collection of U.S. noninteractive digital performance royalties. Copyright exists when each work is fixed, but registering the composition and sound recording with the U.S. Copyright Office creates a public record and can provide important enforcement benefits and remedies.

Once ownership is established, licensing converts those rights into permission for specific uses—such as streaming, downloads, synchronization, samples, remixes, user-generated content, or AI training—by defining the authorized rights, repertoire, territory, term, exclusivity, and compensation for the composition, the master recording, or both. Distribution then delivers the completed recording and its identifying metadata through a label or distributor, making the music available for the relevant rights in order to provide rights owners with clear reporting on what was authorized, how the music was used, and how the resulting revenue was calculated.

Once commercial exploitation begins, collection societies, digital service providers, and administrative collectives ingest usage data to calculate, allocate, and distribute performance, mechanical, and master recording royalties to the verified rights holders identified in earlier stages. At the same time, rights owners must actively audit financial statements, trace unmatched earnings, and deploy technological and legal enforcement—ranging from digital fingerprint takedowns to auditing artificial streaming manipulation and policing unlicensed AI model training—to protect asset value and preserve their revenue streams.
