It's been bugging me for a while now, so I'll just ask for your help. It's played between 1:38 and 1:50. And no, it's not in the OST (at least I think not...).

Thank you. =)

EDIT: I left out the "VII" in "Final Fantasy VII: Dirge of Cerberus"...:(

I always wondered (kind of related) which track on the soundtrack was the EMBU or ATTRACT TRAILER track. The one that plays during the first movie, before you press start.
