This has boggled my mind for some time.  Have you ever noticed that there are multiple classic rock songs that have swear words played on radio stations.  I know there are plenty, but the two I hear most often are The Who : Who Are You and Aerosmith: I forget which song.  Is there some sort of clause or statute that allows them to be played and not modern songs.  If there is its a good thing because modern music sucks.  Cany anybody else think of other songs that have sear words played on the radio?
