All of it.
I'd have to pick out a list of example artists/songs to find out what exactly their genres are, but stuff like Fatboy Slim/The Prodigy/Pendulum/Technical Itch/Rusko etc? I think that's predominantly DnB / breaks but I know plenty of songs of other genres that work with these sorts of games too.
Whilst I do like dubstep, it's probably not made for Grip
So no dubstep.
