Goodness. I recognize quite a few songs, all of the ones by Red Hot Chili Peppers, some random ones like 21st Century Breakdown, and a few songs that I think I know but I'm not sure so I have to go look them up. :D
It's really rather neat. See, if I tried something like this, I'd forget after the first four days and then wake up three weeks later: "Hey! I forgot about it! D:"
Aaaaaaand now I'm off to go listen to some of your, uh, calendar. :)
