Where do I send payment for music copyrights?

You do not send payments directly to a generic "music copyrights" department. Copyright payments are handled through licensing agreements with the copyright holders, usually through organizations such as performing rights organizations (PROs) or music publishing companies.

If you require licenses or want to make payments for specific copyrighted music, you will need to contact the copyright holders directly, obtain the appropriate licenses, and make payments according to the terms of those licenses.
