Sexy Smoothe
It's also not my favorite choreography. I LOVE the pole dancing parts, but the on the ground group moves are meh. The reason I fell in love with Flashback was that beautiful line of choreo that permeated the piece (and went entirely, abusively, ignored in the MV). I've made sure to watch this live a few times before deciding, but really the Choreo's pretty bland. It's sexy, certainly, but nothing spectacular.
I like the song. It's a nice smoothe RnB track. Some people have been saying that it's dull, but honestly it's just slower than most people like to hear. It's a very well done track, lots of power and drive behind it's movement, like inertia verses zippy speed. Over all a pretty great release.
