I was just thinking about this last night as I was trying to get to sleep! Then I fell asleep. It turns out I bored myself into a coma with the subject.
I don't know what it's like really for younger people today with their music choices available. All I do know is that so many kids today really do appreciate many of the old classic bands like Floyd, Zep etc.....So I can only assume there is either something so bad about new music that the kids aren't rebelling against the old stuff, or they are so well adjusted today that they can keep their minds open to older stuff better than my generation did.
