swing

The first time I saw this movie I was young enough (7ish) to not know who Madonna was, but I did know that I wanted to BE that chick in the swing dance scene. 

Also, this is one of the greatest scores to a movie I have ever heard.  And it's Hans Zimmer of course.  If you're ever watching a movie and it's exceptionally great but you can't put your finger on why, just stop and listen for a second.  It's probably the score.  And he probably composed it.
