For those of you who seem a little confused, mizzblue means the music that would immediately start playing as soon as you cast a spell or attack a monster, then it would stop after not attacking for a while and go back to the general music for that area. The battle music was different for a bunch of different areas, which was neat. There's no battle music now, just certain songs that constantly loop no matter what you're doing (like that annoying happy-go-lucky techno one) and the flying music.
But yeah, I miss it too. I used to love the epic battle music that would play around Darkon.
