This isn't a belly dance style. It looks like these women have little or no belly dance experience, although they may have other dance experience. It looks like they just quickly learned a few moves and put them together in a dance that may be belly dance-inspired, but is by no means belly dance. The movements look much too stiff and external.
Hmm... background music is interesting but I agree I don't think those women are professional or semi-professional bellydancers. The movements were way to harsh and stiff. Even tribal fushion with this locks are not as stiff or harsh looking as this.
This is why belly dance isn't just "the moves", IMO. Technique-wise I've seen a lot worse, though subtle it wasn't, and the crotch thrusts were just wrong.
But musicality-wise - ouch, like fingernails down a blackboard. It's as if someone got those moves and just flung them at the music, never mind whether they fit or not.
