The Traverse Town theme from the original version of Kingdom Hearts. I prefer this one over the 1.5 version, just like most of the songs from the KH OST. The piano just sounds too quiet in the 1.5 version, it's almost non-existent.

Sorry for the random pops throughout the song, they weren't there originally when I uploaded the video, so I guess YouTube messed something up. It REALLY bothers me, to be honest.
