Hm I dunno. This isn't strictly a remaster of the original battle music, but more a re-arrangement of it as well. Simply remastering it would just increase the fidelity of the music, giving it a higher dynamic range, cleaner instrument samples, etc. It wouldn't add electric guitars where there weren't electric guitars before.

I don't mind it, though, although maybe there should be a toggle for people who preferred the older versions of the tracks. It's not like a BD can't fit it!
