Harmonix, in an effort to push its forthcoming dance sequel Dance Central 3, has provided Microsoft with a demo for the game, which is available for download now on Xbox Live Marketplace.  Yep, you won't have to wait until later this month to see if you have the Moves Like Jagger, thankfully.

In fact, that Maroon 5 radio hit is actually one of the three songs you can dance to with the demo, as well as Jennifer Lopez's "On the Floor" and Nicky Minaj's "Starships!", in case you feel like making a complete fool of yourself.  (We do that.)

You'll also be able to take advantage of the new Party Time mode, which you can activate by high-fiving a friend to make your own moves.  So if you ever wanted to do a funky chicken to Nicky Minaj, well, here's your opportunity to not be laughed at.  Just make sure you're not around any friends with camcorders, okay?

Dance Central 3 hits stores on October 16th.
