ASCAP

The American Society of Composers, Authors and Publishers (ASCAP) is an American not-for-profit performance-rights organization (PRO) that protects its members' musical copyrights by monitoring public performances of their music, whether via a broadcast or live performance, and compensating them accordingly.

ASCAP collects licensing fees from users of music created by ASCAP members, then distributes them back to its members as royalties. In effect, the arrangement is the product of a compromise: when a song is played, the user does not have to pay the copyright holder directly, nor does the music creator have to bill a radio station for use of a song.
