You have completely overlooked the best battle theme from any game in the history of ones and zeros.

Clash On The Big Bridge.

And, technically, it is a boss battle theme from a Final Fantasy game, so it follows the rules. If you have included it, I guarantee it would have 100% of the votes. Therefore, I have to say you did not include it on purpose.

And don't tell me to vote for Final Fantasy V because that would imply that I wanted the regular boss battle music from that game.

No Clash On The Big Bridge? No vote!
