do you mux?

My little brother showed me this very simple yet very cool site where you can make your own mix tape. You upload up to 12 songs, each having to be 10 MB or less. Then you have your own playlist from anywhere and the interface is so effective. While my brother's is funky and probably has taste, mine is soundtrack based. One of the best parts is to discover what others are listening to and maybe find a new favorite. Loads of fun and just so simple.
