Back when I was in high school (a long, long time ago) I interviewed John Sebastian (not the Lovin' Spoonful John Sebastian, this other guy here, then with KDWB) and he explained to me that music on the radio was intended for people who don't really like music. There are more people who don't (and radio must appeal to a mass audience) and those who do like music, listen to records. If that was true in 1976, today in 2015, with mp3/Pandora/Spotify etc. it is even more true. So I never expect music on the radio to be any good, and if it is, it is a transient exception.
