hmmm quite agree on the whole mainstream music thing. Good Charlotte, like heckler mentioned, is like, "meh"? my friends are like, "better than ure (non-mainstream band name)....."
seriously, i think the music i like is more erm say, mature? coz i like what older people like, not what people in my age like IE red blah blah apparatus, paramore, etc. most of them are punk rock bands. emo bands. oh my goodness.
anyway, the stuff i like are The Strokes, The Hives, John Mayer (he is commercial but hey his blues is the bomb), Arctic Monkeys (i love british guitar bands), Death Cab for Cutie, The Editors, Rachael Yamagata to name a few
