Why did you play this song?

"Base on what you've told us so far, we're playing this track because it features electric rock instrumentation, mild rhythmic syncopation, meandering melodic phrasing, thru composed melodic style and mixed minor & major key tonality"

Pandora is pretty sexy. Internet radio, customized stations. You pick a song, band or album as a starting point, and it'll start picking out songs for you. You respond (optionally) by saying you like or dislike some of it's picks and it'll refine it's notion of your tastes. The above is the explanation it gave me for playing Muse - Bliss after I'd refined my tastes a little bit.

Ooh, just as I'm typing this it picked The Killers - Smile Like You Mean It. *was about to write something vulgar and complimentary, but remembered my mom reads this*

Yay.

EDIT: Oh my again, Audioslave - Dandelion just came up, after some other mixed strange good and so-so I'd never heard of. In case you didn't know, Dandelion kicks a fair, nay, large, nay, HUGE amount of arse.
