"Radio Song" is the fourth single released by R.E.M. from their 1991 album Out of Time, where it appeared as the opening track.
Singer Michael Stipe once said that he hoped everyone had enough sense of humor to realize that he was "kind of taking the piss of everyone," himself included.
Stipe also asked KRS-One, leader of Boogie Down Productions (of which Stipe was a fan), to contribute to the track. He provides some backing vocals for the track, as well as a closing rap, and appears prominently in the video. (less info)
