What, my list wasn't long enough for you?
My list points out that radio and charts were dominated by bands that were not rock. I would also take every pre-Wish You Were Here Pink Floyd album over the 1975-2000 albums.
When I discovered the Beatles in 1975, they stood out from the crap I was hearing (yet it was hippest at that point to snub this band that broke up a few years ago and hype their solo material instead).
Even late 70s rock is not so much rock and roll.
The term has been co-opted to mean "cool music listened to by young people" when so little of it has ANY relation to rock and roll.
