The album's actually pretty good. She just started doing stuff like this on her last album, Style, and this new album, of which that performance was the title song of, is her first to go all out with it (containing only one ballad out of twelve tracks).
She really seems to pull it off well. A couple of songs are so-so, though, like "My Darling", for example, with its Japanese Lil' Jon soundalike, complete with Engrish Yeah's, Okay's, and Let's go's. But overall, it's something worth checking out.
