Keep in mind that radio airplay only pays the songwriters. That's been the case through the history of radio. Neither artists nor labels get paid by radio for airplay. In addition, payola laws were written to prevent payments to be made to radio for airplay without acknowledgement. Those laws only apply to broadcast radio, not digital. So artists and labels get paid by Sirius and Spotify, and in return, artists and labels can buy airplay on those platforms. No payola laws.
The Digital Copyright Act created a payment system for artists and labels for digital airplay. All streaming stations, including those from broadcast radio, must pay those additional royalties. The artists and labels want that law extended to broadcast radio. It would more than triple the royalty payments radio stations pay now. Plus it would cause payola problems. But if they get their way, it's likely that a lot of stations will stop playing music altogether. As it is, the number of internet radio stations has dropped from where it once was, because the royalty payments increase every three years. A few years ago, Live365 shut down because the royalties got too expensive. They figured out a way to come back. But those expenses increase all the time.
This is why radio stations are really focusing more on the content they create, which is news, sports, and talk. That is likely going to be the future of radio, because the music is becoming less focused and less consensus, and there's less money for stations that attract fewer people.
