Kuja's theme from FF9, the Wall Market theme from FF7, and (I know it's not from a Final Fantasy game, but it is a Square game) my favorite, Scars of Time, the Chrono Cross main theme.
I just love the FF8's main theme and the ending... eyes on me was good, Kuja's theme is amazing. I just heard it from the game at the end of disc 1. Some of the musics are so similar in FF10... But they were really good.
