How come Last.fm and emusic both seem to want to keep giving me more and more amorphous hipster crap music? 

There's some good stuff in there amongst the musical tapioca pudding....I got Neutral Milk Hotel and Fruit Bats and Whiskeytown through Last.fm, but for the love of god, otherwise it seems like a neverending stream of ironic guitar crap. Like in High Fidelity, when  he talked about wanting music he could ignore...this is it, baby. 

It comes on, I shut it off and play Townes Van Zandt.
