if you guys like irregular meters, you're going to piss your pants at some of the tracks in my XBLA game. didn't start doing them until much later in the creation of it, and they wanted four on the floor for most of it, but i've got some 7/4, 5/8, 11/4, and x/8 (mixed meter throwdown, basically ) all over it. it's so much fun.
the 'war music' track is all over the map on time signatures. completely impossible to keep track of while you're playing.
