They Help You Make Money
A Music Publishing Administrator manages licensing and collects for you part or all of the royalties your music generates.
By definition, a publishing administrator does not own or control any percentage of your actual copyright. They will simply administer rights on your behalf and collect royalties for you by registering your works in performing rights organizations (PROs), collection societies, and representing you in licensing negotiations with music users. Your songs are all potential assets and publishing administrators help you maximize your ability to collect on them.
