The Chrono Trigger one is barely recognizable as CT, IMO. Not that that's a bad thing, but he really did take creative liberty. It sounds a lot more like KH2 to me.
EDIT:
Also, the entire FF9 soundtrack. 'Nuff said. Of course, I might just love it because it was the first real game I played (I got into gaming relatively late in my life), but it's still awesome.
