The Place I'll Return to Someday, Vamo' Alla Flamenco, Jesters of the Moon, Crossing Those Hills, Hunter's Chance, Kuja's Theme, Sleepless City Treno, Immoral Melody, Eternal Harvest, Extraction, Protecting My Devotion, The Sneaky Frog and the Scoundrel, Secret Library Daguerro, You're Not Alone, Dark Messenger, Final Battle, and Melodies of Life.
I also like the secret track Doga and Unei, though that's technically from FFIII. Oh, and
Kuja 5 which was never actually in the game, but I like it more than the version used in the game. It sounds sad. :
