It might be a bit late to say this, but I think many people haven't noticed: the order of the songs is incorrect. They're correct in the presentation video, but for some reason there was a mix-up in the download package.
The correct order should be this:
Track 02 > 03
Track 03 > 04
Track 04 > 05
Track 05 > 06
Track 06 > 07
Track 07 > 08
Track 08 > 09
Track 09 > 10
Track 10 > 11
Track 11 > 12
Track 12 > 13
Track 13 > 14
Track 14 > 15
Track 15 > 02
