A) I'm not a lawyer or copyright lawyer.
B) I do not know the details of your contract.
C) I'm not an authority in the matter.
With that out of the way, my *assumption* is this: More than just adding a credit to the person or production facility that owns the license, it would be my guess that they would have to be credited as the actual production agency that made the film. Likewise, said production agency would have to agree to those terms. With that in place, I'd guess the use of the music would be completely legal under the contract.
The only catch is, if the movie sucks, the producer/facility is stuck with having their name tagged on it, LOL.
Again, all assumptions on my part.
