You sign up, download the player and you can listen to any music you want or one of the global radio stations or a playlist! I highly recommend it, give
it a chance! If you don't like it then you can easily delete it.
Muziic is way way better than last.fm!
You can change the appearance or search for a particular song the possibilities are endless!

This is what the player looks like (actual size)



There is also a facebook app: Link

enjoy!
