Just saw a screening of Collateral .. enjoyed the movie, but then again, suspense/thrillers are my fave genres. OST was excellent as well ... with lots of hip-hop/electronica influences (definitely the way to go!). The Roots are featured on it. I don't know who else is on it off the top of my head, but the the complete list is available here can't wait for the sdtk to come out! i liked all the other soundtracks of michael mann's films .. so hopefully this one isn't an exception.
