How do you customize your dj on dj hero?

No, it's a shame how I'm a sheet wearing closet racist who sucks dick through a glory hole, and dj hero excludes electronic music. Stupid niggur music sucks

No, not of yet at least but they are thinking about it

Yes, the turntable from DJ Hero will work with DJ Hero 2.

The Band Hero Guitar works on DJ Hero 1 on the same console as the guitar. The guitar only has parts on a minimal amount of songs, though.

Its a nice size, small enough to sit in your lap, but big enough to be able to hit the correctly!
