Ever heard of last.fm? Sanam turned me on to this nifty website this morning, and I frankly can't see how everyone of you wouldn't jump at the chance to join.
Essentially, this website tracks the music you play. You have to download a little monitoring software that gloms onto your iTunes or Winamp or whatever and makes a note of every song you listen to. It then reproduces this information on your profile. The interesting part, aside from letting any of your friends see just how much Electric Light Orchestra you play, is that the service apparently recommends further artists, albums and songs that you might like, based on what you play. (It also apparently tries to match you up with other online souls, but this could still be cool, as long as the cyber-friendship doesn't move beyond song recommendations.) So far, I'm impressed. Think of it as one more way to stalk me.
Check out the playlist from hell at my profile. And please, if we see each other online, don't shy away from me and the ELO.
