payola

Payola, in the music industry, is the illegal practice of payment or other inducement by record companies for the broadcast of recordings on commercial radio in which the song is presented as being part of the normal day's broadcast. Under U.S. law, , a radio station can play a specific song in exchange for money, but this must be disclosed on the air as being sponsored airtime, and that play of the song should not be counted as a "regular airplay".
