I gotta dissagree with ya man. I happen to be one of todays youth. I couldn't give a flying fudgesicle about nu metal. Old school metal was comprised of better riffs and more advanced guitar players.
I think its more of a matter of todays youth playing guitar likeing old school metal and nu metal, and todays youth who dont play guitar likeing nu metal only. People who are into music usually appreciate more than one style of music.
Besides, like I've said before, nu metal is on its way out.
