Have you had enough of Classic Rock?

I guess music is fashion, but still, its a mystery to me how and why America has neglected the jazz.
I can understand the influence of the media, the sex revolution and all the stuff that has changed in the society, all accompanied with ceratin changes in the music, but looking it from purely aesthetic or even better, from quality standards, majority of rock music is a just simple product made for teens.
Todays nostalgia about it only shows that todays music is even worse.
