Here's another google gadget we created called MyPlaylist. It's very easy to use.  All you need to do is enter a MySpace vanity name and you get that user's playlists.  You can play each playlist using the MySpace music player.  It would be cool to know what other people are listening to especially the artists themselves.  Listen to your friends' playlists as well as your own.  Enjoy!
