Track 9 is a mashup. It's the title theme, the Candle World pyramid, something, Cotton Realm, Uboa, and... there was music unique to the end of the game, right? If not, the saving music.

I assumed Track 11 was the music that played in Bloodbucket-san's and e-guy's rooms, but I can't find it on Youtube to make sure.

I wondered about track 11 too, but I just assumed it was a (very obscure) remix of the ending theme
