In the music industry, "Songwriter Master Royalties" refers to the earnings generated from the usage of a sound recording, which are typically paid to the owner of the master recording (often a record label or the artist themselves)¹. Songwriters primarily earn publishing royalties for the composition of a song, not master royalties, unless they also hold ownership of the master recording². Streaming services, for instance, allocate a significant portion of royalties (around 80%) to master rights holders³. Therefore, a songwriter would only receive master royalties if they are also the owner of the master recording.
