An AO mix would definitely be interesting but to be honest, I'm SO glad they didn't touch Sparkle with this project. Sparkle is pretty much epic just the way it is. It's already the perfect Ayu dance tune and it's infectious as hell. I introduced it to my brother not too long ago and he thinks it's the best song ever made.
There are just some songs, in my opinion, that need to be left the hell alone.
