I've been playing around a bit with AudioScrobbler.com. It's a kind of music community site that gives you music suggestions based on what you listen to. Since I just started using it, it's still learning what I listen to via a plugin for iTunes (there are plugins for most of the popular music programs out there for Windows and Mac). Right now it is just building up a profile of me that you can look at. Since I'm always looking for new music things to sample, hopefully this will give me some good suggestions down the road. On top of all that they have various web forums and groups you can join for different music genres and performers. I dig it!
