If he had asked me, I wouldn't have chosen this song from Final Fantasy VII's soundtrack. The reason he chose it is because this is the song he heard constantly as I was level-grinding. There's a switch in Junon you can activate that allows you to fight monsters you wouldn't normally face until later in the game, it's an excellent spot!
Anyway, as it turns out, I'm really glad Blake chose this song. It was kind of irritating in the game, but he's managed to make it awesome... of course ;)
