The reason you should join a performing rights organization is you want to get paid. You want to make money in the music business, you must join a performing rights organization. Because, when a record or music plays on television, in a club or on the radio, there's no way to track who and when that music is being played.
So, performing rights organizations are set up to work with record labels, recording artists, performing venues to pay artists for the use of their song. So, when you listen to the radio and you hear a song by Jay-Z, you're listening because that song that you like is going to be played, but then there's a commercial. That means that that radio station is making money from your song. So, you need to be paid for your song.
So, performing rights organizations go out there, and they are kind of your bodyguard that protects you from being robbed or taken advantage of by radio stations, television stations who play your music and don't pay you for it.
So there are three performing rights organizations you can sign up with. There's ASCAP, there's BMI, and there's SESAC, alright? They primarily do the same things, which is work with radio stations and all the performance venues that play music, to pay artists for the use of their songs. And that's why you should join a performing rights organization.
