This Is My Jam

This is pretty cool.
You can go to this site and make your own jam.
Just create an account, search for some songs, order them, and have it generate the jam. You can use custom settings to control the transitions, or let the app do it automatically.

Here's one I just slapped together:



It's a bit clunky right now. And if I'm right, the music not extracted from each song on the fly, but is taken from the previews at Amazon.com. Actually, I wouldn't be surprised if Amazon was behind the development of this.
Still, I think it's a cool concept.
