lol, the many offsprings of rock and emo....too many to really catagorize, i think, because a lot of bands are very different in their musical style (ie: Alkaline Trio and Dashboard).
I think what people confuse alot are Punk and "punk." to me, Punk is hard core punk, like the bands that started out in the '80's. "punk" is bands like MXPX, who have a punk style, but are not hardcore Punk. And since Emo just started out, it's kind of hard for people to really tell which is emo and which isn't. okay so the emo and punk analysations had nothing to do with each other but umm....they make me feel smart so we'll keep 'em :-P
