BoA - Energetic

Okay I gotta get back to work. This choreography looks a lot like Paula Abdul somehow. But I have no complaints about the song, which is fairly happening and has some great production. Apparently this woman (Beat of Angel, or BoA) is the shizzle dizzle in Asia. The wonder of autotune/vocoder vocals renders her voice so synthetic that's it's sort of a global hip hop dance sound.

Check the choreography in Eat You Up, below, too. I can't decide if it's comically stale or refreshingly retro.

Question: why is it, in these videos, that there is always a white guy with an old hat as one of the backup dancers?
