Maybe the problem is with me. I thought it would be ONE CD with the tracks as they are and ANOTHER CD with the rearranged tracks.
Anyway...
I assume that the numbers before the names refer to the number of songs a certain movie had. For example, I think Mujun Rasen has 4 songs in this tracklist:
9. Ⅰ magician
10. Ⅱ paradox
1. Ⅲ spiral
2. Ⅳ paradigm
If this is correct:
2. Thanatos - obviously Fukan Fuukei
3. Ⅰ something and nothing
4. Ⅱ quiet romance
5. Ⅲ rain goes up
Satsujin Kousatsu (Part One)
6. if I cry
Tsuukaku Zanryu, most probably M19+20
7. garan-no-dou
obviously Garan no Dou
3. when the fairy tale ends
Obviously Boukyaku Rokuon
4. Ⅰ everything, not nothing
5. Ⅱ into the light
6. Ⅲ epilogue
Satsujin Kousatsu (Part Two)
And finally the last two for the epilogue. I think in the garden of sinners may be M01 from the first movie, but since it's kind of KnK's main theme they didn't count it as one track for the first. Same with kyoukai-Shiki, most probably Shiki's Theme.
