Just thinking about that some more, I think a few things could be added:
Song I'll listen to repeatedly: Elevation, U2 is the current one of these. Or How You Remind Me, Nickelback.
Driving Music: Surfing with the Alien, Joe Satriani
Song that best describes my college life: 3am Eternal, KLF
Song that makes me sad: Don't have one, but I'm sure some of you do. Song that makes me happy: again, don't have one.
Song I'd most like to hear again but I don't know what it's called: A song Dave Fanning played on his radio show years ago, which may or may not have been by "Mr. Food" but was basically a guy with what could have been a Northern England accent (think Yorkshire) listing off quantites of food he'd eaten. It was very funny, and I never heard it again.
I'm sure you can think of more categories. Don't let the meme stagnate!
