Well, I remember the two being different in the past (the bonus stages definitely had a different music in the demo than they do now in the full version I have), but for some reason, they took the music of Exoticus when I installed all 9 episodes. Listening to you guys, I'd have to conclude that this isn't supposed to happen (ye gods, my JJ1 has been living a lie for the past few years. OH THE HUMANITY O.o)
