Favorite song from the parks?

[SewIn2Disney]

So... What's your favorite song from the parks, that's not from a Disney movie?

I'd have to go with the Future World music in Epcot.

Starting at 5:55, just awesome. Always gets stuck in my head when I'm walking through Epcot (and right now).

That EXACT part is the first thing I thought of when I saw the title of this thread. That is my favorite background music in all of WDW---I have it as a ringtone on my phone, and I play that as "brain music" for my students while they're working....I could listen to it all day long!
