Royalties For Musicians

AFM & SAG-AFTRA Intellectual Property Rights Distribution Fund
AFM & SAG-AFTRA collectively entered in a variety of negotiations and agreements with various organizations to secure royalties for non-featured performers (e.g. sidemusicians and background vocalists).  The AFM & SAG-AFTRA Fund does for session musicians and background singers what AARC and SoundExchange do for featured artists.
The Alliance of Artists and Recording Companies (AARC)

The Alliance of Artists and Recording Companies (AARC) Is a non-profit organization formed to distribute Audio Home Recording Act (AHRA) and foreign royalties to artists and record companies, and is the leading common agent representing them.

SoundExchange is a nonprofit performance rights organization embodying hundreds of recording companies and thousands of artists established to license, collect and distribute public performance revenues for sound recording copyright owners (SRCOs) and artists for non interactive digital transmissions on cable, satellite and webcast services.   Prior to 1995, SRCOs in the United States did not have a performance right. The Digital Performance in Sound Recordings Act of 1995 and the Digital Millennium Copyright Act of 1998 changed that by granting a performance right in sound recordings.
