uPlayMe. Download the client, and it’ll see what music you’ve been playing on your computer and hook you up with like-minded music lovers. I don’t know, is this useful? Any more so than PandoraFM? You decide.
Now there’s a simple way to meet people and find new music just by playing songs on your computer and iPod! Download uPlayMe (it takes less than 15 seconds on a cable-modem), register, and that’s it! As you play music, uPlayMe finds people who are playing the same music and shows you what they’re listening to. You can chat with them, visit their pages on other sites like MySpace, or just find new music to listen to.
