DJ Karaoke 
We know the ruthless dictator in you is dying to bust out the REO Speedwagon playlist come NYE, but why not put music in the hands of your guests this year with DJ Hero? Like its guitar-version big brother, DJ Hero's simplistic, color-coded turntable (think of it as a fun version of Simon) and crossfader allow you to mix and scratch with the deftness of Grandmaster Flash himself. With 102 tracks currently available, from French electro whizzes Daft Punk and Justice to classic cuts from the Beastie Boys, 50 Cent and even Marvin Gaye, DJ Hero allows your paws to control the parties seamless soundtrack. Everyone will be vying for mixing mastery, that is, when they're not getting down to all the sweet jams afoot.
