You guys hit it right on the head as far as airship themes go, FFVIII had awesome music when you're aboard the Ragnarok, I mean come on it just made me wanna go speeding off into the distance to discover what was in store for me haha. To Cactuar Island! lol

As far as World Map themes go I like FF IX's theme song in the World Map but before the Mist covers the entire world. I always wished that I could change the theme song back to what it was when I get back from Terra every time I'm doing side quests and training on the 4th disc lol
