Yet, Classic Rock stations continue to fare very well in the ratings and attract good numbers in younger demos (in a lot of markets). This is new music in some cases to the younger crowd; for a 57 year old geezer like myself, it’s about the music and the era.
Carly Simon and others in that genre were played in the early FM Rock (Progressive days); those stations had a loyal, but small core. Once the stations morphed into AOR (or a competing station did), the ratings climbed. The fact that a lot of good music was being released also helped the AOR format greatly. The core artists of that time frame (Zeppelin, Skynyrd, Van Halen, AC/DC) are now the core of Classic Rock. The arena rock bands and harder rock bands were popular with the “new generation rocker”: as a result, the Carly Simon, Joni Mitchell, Harry Chapin sound wound up being removed from the playlists.
