Mitsuda definitely wrote Pleasure Cruiser, it has
his style all over it. Especially the style he used on
Soma Bringer and
Inazuma Eleven. (the basslines in particular)
BTW Jormungand, would you have any interest in doing this type of breakdown on Bomberman 64: The Second Attack? It has quiet of few composers though.. (Tomohiko Kira, Yasunori Mitsuda, Hidenobu Otsuki, Tomori Kudo, Hiroyo Yamanaka, Yoshitaka Hirota, Kenji Hiramatsu)
