Does anybody know where I could find a composer-to-track breakdown of ZX Tunes, for example 'Trap Factory by Ryo Kawakami'? Combing various sites has revealed breakdowns for every Zero/ZX album but that one.

The booklet gives a full breakdown:

Disc 1
Ippo Yamada: 1-2, 5, 7, 12, 16-20
Masaki Suzuki: 3, 4, 10-11, 14-15
Ryo Kawakami: 6, 8-9, 13

Disc 2
Ryo Kawakami: 1, 3, 7-10, 12-13, 17
Ippo Yamada: 2, 4, 6, 11, 14-15, 18-19
Masaki Suzuki: 5, 16

Ah, many thanks.
