Aguilera recruited her Voice colleague Cee Lo Green to duet with her on this electro-soul track where the pair invite America to 'turn down the hate.' "I got to collaborate with my good buddy Cee Lo," Aguilera said at an album preview event. "There was a part for a potential male vocal on the chorus, and I just heard immediately Cee Lo's voice on it, his signature Cee Lo, and it was fun collaborating with him and having him on my record and us joining forces together."
"The Night Chicago Died" was written and recorded by the British group Paper Lace. They talk about Al Capone in the song, but got a lot of details wrong - understandable since they wrote it based on gangster movies.
