Some great points here!
The forum here is much like any other part of society where people get this concocted (sp?) image in their head of what people around them should like, and what they should not like. It all goes back to "class stereotypes." I am equally guilty as the next person of lumping people into categories by what music they like or how they dress, etc. etc. And people will specifically not liek a band because THEY have put them into a category. I think it would be an intersting sociology expereiment/research project.
But, U2 is a band, because of it widespread popularity, that cross many styles of music. Just think of how many different radio station formats play U2 - you can hear them next to easy listening favorites or after a hip hop artist on a Top 40 station, or next to Metallica or AFI on a local college station (FuManchu knows what I am talking about with 107.1 the Planet in C-U).
Cheers to those who start threads about "other" types of music!
