Lol it was one of then better trailers I saw last year. When "Am I wrong cause i wanna get it on till I die" drops, I'm bobbing my head and it's just perfect atmosphere music for those action scenes. So effective for setting the mood. Seems like a waste not to use it in the movie. But then again I get it, you hire someone to make a score for a reason. BP was 90% score(Great one by the way) 10% Kendrick... Maybe less.
