Sorry for the increase in Youtube video posts, but this is actually a really great arrangement of this song. The original version by Usher is my current guilty pleasure (along with Ke$ha's Your Love is my Drug... Fuck!), and yeah... I've been reluctant to acknowledge that Usher has made any good music since his old music like, ten years ago (think U Remind Me, U Don't Have to Call, U Got It Bad), but this song is winning me over. David Choi's cover is awesome, too.
