now as it was in the '80s and '90s, IMO (I'm including some rock from the late '60s in this too, when I mention "'70s rock"). And '80s rock is barely less popular than it was in the '90s and '00s.

My kids (in their teens and twenties) listen to a lot of music from that era, and are familiar with almost everything that was really popular back then. It's weird. Very different than when I was their age — I listened to essentially nothing that my parents liked or listened to. I probably couldn't name more than 5 songs they liked (and those were almost all from the Carpenters, a '70s band).
