I suppose I like a lot of mainstream bands, because I don't really care whether a band is mainstream or not. I listen to what I like, really. Most of the bands I like now are just outside the mainstream, fairly obscure, or were popular a long time ago, but aren't anymore, really. However, I do enjoy System of a Down, The Mars Volta, and Radiohead, who as far as I know, are all fairly popular right now.
