I can't remember all those different battle themes! (And some I haven't come across yet...)
Does Yojimbo's music count? That's cool, I kept summoning him just to listen to it
Oh I think I liked Yunalesca's battle music too.
In general I just like all battle music it rocks but it's scary when you hear the boss music and realise your fighting a boss..(If you didn't already realise )
