My weird internal soundtrack

One thing I noticed in the past is that, when I was in a really good mood, the two songs that had the greatest tendency to pop into my head were singularly inappropriate: Black Sabbath's "Paranoid", and Nirvana's "Lithium".

Paranoid's wandered out of that playlist, probably due in part to Rock Band, but Lithium's still there. The Who's "Behind Blue Eyes" may have joined it, but I'm not sure yet -- I've been on a Who kick recently anyway.
