Pokemon Black & White - N and Ghetsis' Battle Themes Overlayed

It occurred to me while listening to the Pokemon Black soundtrack that Ghetsis' theme seemed like a lot of background instruments with no melody. At the point in the game that you hear it, N has just defected and Ghetsis is outraged, having lost the pawn he was manipulating from the background--being the support, but not supposed to be noticed. So I wondered if overlaying their battle themes would show that Ghetsis is the background to N. It worked, for the most part.
