since the late 40s, ASCAP has required licenses for airplay, and the broadcasters created their own licensing agency, BMI in the 50s. when I was growing up a broadcast brat, the music director weeded out incoming discs that were not of those two organizations (CAPAC in Canada later reached a deal with ASCAP to collect their royalties), and counted up the needle drops. nickle a drop in those days, it was raised to 7 cents a play in the 70s. stations cut their check every month to the agencies.
in the past dozen-odd years, BMI in particular has been putting boots on the ground, checking restaurants, coffee shops, doctors offices, whatever to see if they had a reuse license for music. if you had Muzak or 3M service, they walked out. if not, and you didn't have a license, it was mafia time... sign a contract right there, or you're sued. it applies whether you have your own discs or tapes, or are playing the radio.
recently outfits have been putting up their own music streams across their chains... "Subway radio" "LA Fitness Network" and so on. if the HQs don't have their licenses, as Muzak and 3M arranged, they are up shit crick.
why this bozo congresscritter didn't do any research of his own... oh that's right, their instructions are in the envelope with the cash... well, he's an idiot.
