Well I definitely have a few myself, obviously FFVII, FFXI, Tactics, Chrono Cross, Saga Frontier, and Legend of Mana. However I'll link a few of my favorites from non Squaresoft IPs.
On the top of my list would have to be the Alundra OST
, Particularly the US Opening Theme
(and accompanying movie). Not many games had this quality of music, especially Kline's theme, the child's theme, and the lake shrine theme. It was also interesting to note that the sad song they play when people die in Alundra was also the theme of some female thief character in Legend of Legaia. It was quite funny hearing that song in that game.
The Lunar Silver Star Story was also a personal favorite OST of mine.
I was going to think of more to list but I just got a certain email and died.
