I probably wouldn't be lying if I said I liked the entire soundtrack

"Man With the Machine Gun"
"Force Your Way"
"Hunter's Chance" (I know that was in this game...right? When NORG tries taking over Garden?)
"Premonition" (sp?)
All the final battle themes, especially "Maybe I'm a Lion" and "The Extreme"
"Roses and Wine"
"Eyes on Me"

...I'm going to make a huge list, so I'll stop now. This game had one of the best soundtracks to an FF game, IMO
