Hah, I wouldn't think of implying such a thing. You, kind sir, seem as un-hip as they come.
I don't usually like to reveal my musical tastes, as I think they make me seem like a tool, but here's a sampling of some of my favorite bands: The New Pornographers, (some of) Arcade Fire, Rise Against, The Who, Belle & Sebastian, and (most embarrassingly) Billy Joel. Basically I'll listen to everything once; I don't have discriminating tastes as much as I have no taste.
I didn't realize your music reviews were linked; I am off to read them now. Other than what you've reviewed, though, what bands are you into? Perhaps there's some overlap, considering my, uh, catholic, wide-reaching tastes.
