Sweet!

I like this a lot, it's not your typical "Hey let's go party" kind of dance. It's definitely got a mood to it. :)

Only real complaints are the buildup kind of suggests a BIG drop, which wasn't as hard as you expect, and the end is very empty, but I'd assume you were going to put something there if you finish it.

Overall though, it's a great start, you should keep working on this though, it could turn out really well.
