For several decades now, radio stations have been exempt by statute from having to pay royalties for playing sound recordings over the air. This was from a time when radio stations actually promoted music over the air. Over time, this trend in radio had shifted in this country. Gone are the days of the "boss jock" or the "good guy" who would not only announce the song, but even say what label the song was on. Music on the radio has become more institutionalized, especially in the face of streaming services that have no DJs and allows you to skip songs that you don't like.
