I was thinking 'tension' and 'resolution'. If you take the them of a song and say okay is it a resolved issue or does it leave you hanging in the balance it kind of directs how you can flow with it musically. The verses in I'm so excited on their own have this dark tone to them, but its because of that that the excitement is so powerful. You know you've arrived at a release. A balanced yin yang. You gotta feel the tension in order to know the release. And then you have the end where it shifts up in key to take you even higher!!

Fiona Apple's "Warewolf" is another great one... After all when a song ends in a minor keeeeeeyyyyyeeyeyeeeeeyeyeyyyyy.
