I hate anything that people just jump on the band wagon for. Greenday would be a prime example of this. They had some good stuff way back when no1 knew them, then they release this new POS album that gets a lot of publicity, then everyone started being a greenday "fan". That's when I started to hate them and most music thats popular these days. so I switched to classic rock.

personally, i do like the Beatles. now I'm not just one of those fans that knows all the popular songs by them, I have all their songs in my music collection and like to listen to pretty much all of em. they have an amazing variety of sounds and influenced a lot of the ways music was made after them.

other crap bands off the top of my head: nickelback, FOB, simple plan, Panic! (used to like them), the new Blink 182 stuff (old school ftw)
