hope i'm not reviving too old of a thread here, please excuse me if i am, i apologize. . i just beat final fantasy xiii not long ago and wasn't crazy about the gameplay or storyline as much, but i really liked some of the tracks. my favs are

sulyya springs
chocobos of pulse
will to fight
menu screen theme

especially those last 2 tracks perfectly beautiful got the menu screen song as my ringtone it took the place of link to the past - dark world theme lol
