 In July 2005 , composer Tyler Bates begun work on the film , describing the score as having " beautiful themes on the top and large choir , " but " tempered with some extreme heaviness . " The composer had scored for a test scene that the director wanted to show to Warner Bros. to illustrate the path of the project . Bates said that the score had " a lot of weight and intensity in the low end of the percussion " that Snyder found agreeable to the film . The score was recorded at Abbey Road Studios and features the vocals of Azam Ali . A standard edition and a special edition of the soundtrack containing 25 tracks was released on March 6 , 2007 , with the special edition containing a 16 @-@ page booklet and three two @-@ sided trading cards .
