Still More Fighting (boss theme) is my definite favourite, but many many others come close. Those would be:
Fighting (it never gets old), Aeris' theme (like many mentioned already), Cid's theme (it's so inspirational), ShinRa theme and ShinRa army wages a full scale attack (both are nice atmospheric themes), You can hear the cry of the planet (very very atmospheric and somewhat twisted, especially if you know what's about to happen when you hear in game), Great Warrior (the music complements this touching scene really well), One Winged Angel (because it's epic), Sandy Badlands (it's pretty atmospheric too and suits the killer desert really well), Main theme, Who am I (oh this is just very twisted sounding tune), and many others. In a somewhat weird way I also enjoy Rufus' welcoming ceremony, because every time I get to Junon and hear it, I start making up lyrics and sing them to the song.
