I'm going with "Watchmen--Main Theme".
I don't think it will be a licensed song. Movies usually go with original score at the beginning of the credits, with the licensed songs coming later.
How about the Velevet Underground?
Peter Gabriel - Red Rain
Duran Duran - Wild Boys
Or something with Depeche Mode or Human League.
V for Vendetta's credits kicked off with Street Fighting Man by the Stones.
Culture Club- Do you really want to hurt me
How about Requiem Lacirmosa by Mozart?
Absolutely loved the beginning and the end of that, although the middle was a bit haphazard for me. Your own work?
