The only thing that could cause one to not enjoy this song is the fact that the vocalist is naturally sharp or flat of the instrumentation (I'm not sure which, but I'm going to guess sharp), but for the most part, it does little to detract from the overall quality of the song. The key change is the very standard whole tone up, so nothing out of the ordinary there, though it is a little sudden. Of course, the song just makes me want to dance. The world needs more Bust a Groove remixes.
