Chaotic Heart was one that in retrospect, I feel I should've said "Hey Sixto, can you plug a real ending into that one?" Still though, it is one of my personal top favorites on the album, simply because it takes the original and runs with it in a direction that I didn't expect, and also goes a different way from what we usually hear from Sixto. It reminds me of some of the more deliberately paced tracks from guys like Vai or Satriani, where the point is to show off the chops of the guitarist. Probably helps that Raine is my favorite character in Symphonia too, and this remix is quite fitting for her.
