If you noticed though, all the themes I chose for the final round are remixes, arrangements, and piano versions so as far as I'm concerned, its just about the music itself, not the exact version of it. So if you like a different version of one of the themes, at this point its about the theme in general. Basically, say for some ungodly reason you didn't like the original version of Battle on the Big Bridge but you love the remake of the song from XII more than water and air then it is alright to choose it cause its not about the original versions going at each other at this point.
