Famitsu.com got another one of those Catherine exclusives today. This time, the site was given first access to the game's opening.

The opening is really just a staff roll. It lists the following voice actors and staff:

• Koichi Yamadera
• Kotono Mitsuishi
• Miyuki Sawashiro
• Hiroaki Hirata
• Takehito Koyasu
• Kisho Taniyama
• SHOW [PENTAX]
• Masaki Terasoma
• Junko Minagawa
• Norio Wakamoto
• Animation Works: Studio 4C
• Chief Designer: Kazuhisa Wada
• Chief Programmer: Yujiro Kosaka
• Art Direction: Shigenori Soejima
• Music: Shoji Meguro
• Directed By: Katsura Hashino

i think the perfect music for this would be Jazz , not Rap.

Quoted For Truth.

Well Jpop is normally crap but it worked perfectly for Persona 3, no reason why same can't happen for Catherine.
