The first time I heard the battle music in Ni no Kuni: Wrath of the White Witch, I thought, "Ugh."
That's never a good sign. In a Japanese role-playing game like Ni no Kuni, the battle music is arguably the most important music in the game. Sure, the world-map music is crucial, but it's the battle music that you're going to hear over, and over, and over again. It's the battle music that will accompany your many victories and defeats, and so it had better be good. Persona 4. Final Fantasy VII. Trails in the Sky. Many a JRPG has made a mark with its excellent battle music.
