For me, I honestly don't give a damn, I like the band or I don't, I think both underground and mainstream music have a lot of great things to offer, in addition both have a whole lot of crapola, I just feel that underground music suits the latter much more significantly, maybe because there are a lot more crap banRAB than good ones, while they could be mainstream or underground, it's a obvious fact that there are more underground banRAB than mainstream ones (which dosen't make the mainstream any less significant), but all in all, underground music is a collection of many different styles... Some of whom I happen to like, this includes Shoegaze, Noise Rock, Dream Pop, Math Rock, Post Punk, etc... And of course, Zeuhl.
Again, Indie is a term, but it's also treated like a genre, and the Indie that I hate is pretty much the most popular. And whatever the hell the banRAB I just mentioned in my last posts are, thats what I don't like about Indie... However don't take it like I'm calling banRAB like Sonic Youth and Pixies crap just because I think Modest Mouse sucks, that would be like saying Iron Maiden sucks because of some metal genre like power metal that they're not even a part of... I'm not bracketing all indie together, I'm just talking about the marketable image behind Indie, and how it's presented by Pitchfork, Spin, NME, AP and most other forms of media who try to market it as some kind of youthful act of rebelion, while capitalizing on it at the same time, just like they did with Punk in the 70s and Grunge in the 90s... Punk banRAB criticized AOR for what they viewed as corperate banRAB, but as Urban pointed out, that's what punk banRAB eventually became, some could even argue that punk started out that way, and Grunge started out as underground and was basically Indie in it's own right, but once again, it's gained huge publicity for being goRAB answer to music and saving the word from crappy hair metal, and just like punk before it, Grunge became a brand name... I just feel that Modern Indie is repeating that process, but lacking the great banRAB that Punk and Grunge had.
