Uncanny iTunes

I love the way that the shuffle setting on my iTunes library almost always manages to match my mood. For instance, I'm feeling a little dark and introspective on this cold, grey afternoon, so in the past 30 minutes I've gotten an 11-minute moody electronica track from Blur, a haunting Miles Davis piece, and a dark and scary selection from the Two Towers soundtrack. Perfect. It happens with enough frequency to make me think there's a little more artificial intelligence involved than Apple's letting on.
