Ah yes FFVI was such an exellent ost so many memorable tracks. Dont get me wrong FFVII had some great tracks aswell including the best character theme perhaps in Aeris, but not every track was great like that in FFVI. FFIX was also great I managed to pick up a copy of this in my local import store and enjoy listening to it every day
(gets me ready to start the day) tracks off the top of my head like "Freyas theme" and "Your not alone".
I dont consider FFX a traditional ost as Nobuo Uematsu didnt really compose enough of the tracks
although even the ones he didnt turned out exellent. Memorable tracks for me include "Sir Aurons theme" and the fianl Seymour battle and who could forget the "At Zanarkand" track. With that though I think they made a right hash of the Prelude and the chocobo theme.
