At least you eventually got what I was getting at.
I'm talking about the people who hate mainstream music simply BECAUSE it's mainstream. People who like a band, but stop liking them once they become popular. Then you'll hear them say something along the lines of "I knew about so and so band a few years ago. They were good until they started playing all radio crap."
It's like they feel superior knowing that they knew about a band first or that they have superior taste because they like things that most others don't. It's become more trendy than pop music itself and it's annoying.
The issue for a lot of people is that a lot of good bands, once they start getting a little bit of media attention, completely change their style of music in order to become more famous. There's nothing admirable about a band that obviously loves one style of music (the kind of band that they decided to start in the first place) and then a few years later they're playing screamo, because that's what all of the teenagers who buy lots of CDs like.
