ProjectPlaylist
A website where you can browse different music and add them to your playlist. You can post this playlist anywhere; MySpace, Gaia, Facebook, ect. Anyone can listen to the music you put on your playlist. You can have up to 100 songs, custom-make the playlist design, and have a shuffle option. ProjectPlaylist is free and great if you hate having to change your one pathetic song on MySpace over and over again because you like so much music.
I changed my MySpace song 68 times in three hours today, so I think I'm going to just put all of them on a playlist at ProjectPlaylist.
