I should probably add that on a "scaled" scoring that aimed to have a bell curve of soundtracks by how much I like 'em topping out at 5.5 (which isn't how I think soundtracks are actually distributed), Mana Khemia 2 would probably be a 3 or 4. However, I'm ranking 'em like games, so 6 it is; it's still eminently listenable and has its moments, even if it's lacking in "totally awesome vocal / boss tracks" that Gust sometimes nails.

Best Song Standalone: Terra (WoB Overworld). Honorable mention: Dancing Mad.
Worst Song Standalone: Metamorphosis? (The "escape" music.)
Best Song In Context (ie, song used the best in-game): Kefka's theme. Really helps sell the character. Honorable mentions: Under Martial Law, a song that does some very fine "occupied town" work, and the opening snow march music, nice & foreboding.
Worst Song In Context: Battle. It's okay, but doesn't really hold up for the piece that gets played the most often.
Overall Impression of OST: Fantastic for the SNES... except for the battle & boss battle themes, which is unfortunately a pretty significant hit. I mean, they're fine, but they're among Uematsu's weakest, Dancing Mad excepted. Atma Weapon battle is okay, at least. Still, this is nitpicking, lots of utterly random pieces on the soundtrack could easily have been the best pieces in a weaker soundtrack (Kefka's Tower, Thamasa/Strago, even the Ragtime interlude music.... all solid and well-done and memorable, and they're "median" pieces.)
Final Rating: 9/10.
