i spose u could say theres a few ways of looking at it !!
a)hes not dancing to "the" beat,basic 4/4 natural heartbeat rythem that most dancers of electronic music throw shapes to (ie poppers lockers streetdancers etc etc)
b)im not crunk and i find crunk isent programmed to dance to its "notice me " music in the way the bass drum is pounding ,high end noises and some dude repeating simular bars for 3 mins , hence the followers of this music will do the same ,, dance is a form of exspression and exspressing himself he is , but in a oow "look at me im cool way"
each to there own ... fashion not function in my view !!
