This question is not to get into an argument. It's quite apparent. If you take Billboard's Top or Hot 100 albums or songs it's slim pickens for rock of any type to be on there. During the 70s what type of music overwhelmed the charts? Rock, around 80%. The cries may have been "Rock and roll is here to stay" and "Rock and will never die" well...it did. And we all know what swamped it. The lowest form of popular music in my lifetime (you know what) and diva music. I'm not however even debating quality of music just one form's extinction in the same way that American's popular music of the 40s, swing and big band died (needless to say, on the charts, not in people's hearts.)
So I really don't know if there was an exact year or perhaps decade, were it failed to be the music for tens of millions of young people. Any opinions?
(Yes, I would say I listen to some form of rock almost everyday.)
