Forget it guys, they will vote on the side of the money.
BMI, ASCAP and SESAC have the royalty copyrights to all music and they will collect on it. It's not the recording artists that they collect for, it's the songwriters.
They started charging retailers for playing broadcast radio in stores years ago. The average convenience store pays around $600 a year if they are caught playing a radio where customers can hear it unless they have a contract with the publishers.
The charges also apply to live music venues. One bar I worked in was forced to pay over $3000 in fees and penalties. Trust me, they send lots of people into lots of places to listen and they always win in court.
The only alternative to the music nazis is muzak or satelite radio. It's a little bit cheaper because they bundle royalties among subscribers.
