Muscle Shoals Sound Studio Documentary?

On Thursday in class we watched a documentary on the Muscle Shoals studio, I think, and I thought it was a really good film. It's ridiculous how many hit songs and stars came out of that studio, and the manager of the studio was always able to come back after losing bands and musicians. I though it was awesome how he used both black and white musicians and singers and how they cooperated and worked together and all of this was in Alabama. I liked multiple songs throughout the documentary, but I can't remember what they were called.
