No argument from me there...and I think you are giving the classic rock stations
too much credit...it's more like the same
3 Beatles songs, the same
4 Zeppelin songs, the same
4 Stones songs. One of the classic rock stations here, 103.5 The Fox, will sometimes during the day play a "Deep Cut" from an artist....and then when it comes on it ends up being a mainstream song from the band
