Wow, lot's of music snobs? Listen to what you like and like what you listen to. I think I've heard that somewhere
On a side note, before you trash the music that someone else grew up on remember that YOU have MEMORIES tied into what you like. Hanging out with friends, getting laid, etc. Things that make that music special to you. Kids now are tied into the music THEY grew up with. As far as most of them are concered Classic rock is the crap that thier dads made them listen to in the back of the car on the way to grandma's house ( I have an extreme hatered of Roger Whitaker thanks to my dad)
Personally I enjoy both. I used to work at a radio station and the PD always said "Never trash any song you don't like, because it's someones favorite tune."
