I was thinking along the same lines, Ol' Pal. The more I thought about this topic, the longer my list grew. The list of artists/bands I get would probably be a much shorter list due to my horribly narrow and stupidly opinionated tastes.
The fact that there are many genres, bands, and artists I don't like says much more about me than it does about them. I know that just because I don't like something does not mean that it is inherently bad. It only means that I don't like it.
I like Rush, but I don't like everything they've ever done. I like Dream Theater, but not all of their material. I like some pop. I like hard rock. I like some quirky, weird stuff. I'm picky and narrow minded. Everyone tells me that this means that I'm somewhat less of a person than I would be if I embraced all genres equally. I guess I'm subhuman, then. I'm okay with that.
