Launchcast is the coolest thing ever (launch.com). You sign in with your yahoo name and then you can design your own radio station. So you choose the artists you want hear and they play them. Then, you rate each song, artist, and album and that way it won't play a song that you don't want to hear. Also, you can skip over songs, so its like playing downloaded music without downloading the music and dealing with grokster and loop versions and all that. Also, since I'm at the library it has been my life saver. Ok, onto hour 5 no wait, 6 of library time!
