A really fun site that lets you play with music. Includes a music mixer, which allows you to upload a song onto the player, and then using volume sliders, isolate certain beats, sounds and melodies in the music and play them. You can even save your unique “remix” of the song, upload it to a HUGE database of other mixes, and download other users “mixes”. After saving your version of the song, you can email it to your friends. This site also has another version of the music mixer, the Duo Mixer, which allows you to mix music over the net with your friends. If you have a webcam you can even watch others on the screen as they mix music and talk to them via the provided chat function.
