last.fm recommendations=99% inaccurate

Most of last.fm's "we think you might also like these artists" recommendations are complete misses. Even though I know this, my curiosity still pushes me to check out their suggestions. And every time (except the one time I was directed towards School of Seven Bells) I'm always like, "what. no." The end.

For instance, based on Heads We Dance, last.fm thought I should check out Purple Crush. Major disappointment. I did find this fabulous picture of the duo though. So sexual rawr.
