There are a few other songs that make feel really good, but the one I can think of the moment is "Freedom" by Wham! (NOT by George Michael - that is a different song) It just gives me a really happy feeling when I hear it, it's a nice song.

Also... it makes me think of Final Fantasy a bit - that's not the only reason I like it though. (I mean the tune sounds like Final Fantasy a bit, at least in my opinion).
