There are tons of bands I used to like but don't really anymore because of the people I associate with them. The Vaccines, for instance. Their music is still OK, but not earth-shatteringly wonderful as it used to seem. There was this one especially smarmy bastard (whose name I won't mention for obvious reasons) who liked them too, and to escape from that person's taint I stopped liking the Vaccines. My music tastes in general have shifted. I don't really dismiss genres based on prejudice as much- I like at least *something* from pretty much all genres these days, and am much more selective in what I *do* like. I like Eluveitie, Ensiferum, Heidevolk, Nightwish, The Agonist, Solar Fields, Metric, Modest Mouse, Arcade Fire, Dual Core, Menteroja, Mega Drive, Rage Against The Machine, Kraftwerk, and Faun. There are others, but the list would be too long to mention them all.
