I find it interesting that the main melody starts as a variation on FFV's battle theme. While I admit it gals a bit flat (I still think VII has the best regular battle theme in the series), I do like it substantially better than V's, if only because it's longer and more varied. As in, now it's ABAC (or ABAB'? Not really sure how to classify it) instead of plain AB.

The boss themes, however, are exceptional! I know everyone loves the main boss theme, but my favorite is probably the one that is used when you fight the Ultima Weapon. It's criminally unserused. There's this crazy piccolo flute there that just makes the whole track seem so urgent and energetic! And Grand Finale is also beautiful and also underused.

And Dancing Mad. Hoo boy. That's a ton to analyze. Might return to it. I think it's the best final boss theme in numbered FFs. Really ambitious, it pushed the limits of its medium.
