I guess I'm not really naming "standouts", just songs I really like. For the most part I agree with Crawl and FO, plus:

From CT:
Bike Chase (okay, it's really short)
Singing Mountain (Okay, you're not going to hear it in the actual game, but I still like it)
World Revolution (I actually like it a little more than Final Battle)

From FF6:
Edgar & Sabin (maybe it's just my soft spot for the brothers)
Mt. Koltz
Phantom Forest
Devil's Lab
Blackjack
Fierce Battle
Dancing Mad 4.2
