Today's Piano Puzzler

This week's contestant is Susan Liebeskind from Atlanta, GA. It's a tough one.  For reasons i can't explain, I got the composer whose style it's written in.  Sort of a lucky stab in the dark.  You can hear the hidden song, and it's somewhat known, but it's difficult to get, I think.  But the number vibrant and fun to listen to, whether you get it or not.
