 Burlesque : Original Motion Picture Soundtrack comprises ten songs : eight performed by Aguilera and two performed by Cher . The soundtrack has a " brassy , jazzy " sound inspired by jazz , in contrast to Aguilera 's last electronic music @-@ inspired studio album Bionic ( 2010 ) but similar to her fifth 1920s , 1930s and 1940s @-@ influenced studio album Back to Basics ( 2006 ) . Four of the songs performed by Aguilera are cover versions , two of Etta James ' works : " Something 's Got a Hold on Me " and " Tough Lover " , a cover version of Marlene Dietrich 's " Guy What Takes His Time " , and a dance version of " The Beautiful People " by Marilyn Manson , including the " unmistakable " drum beats and guitar riff in the original version . " I Am a Good Girl " " sticks to the sassy swing of a bygone musical era " , while " Express " has the similar musical style to Aguilera 's previous single " Lady Marmalade " and lyrically evokes sexual theme as Aguilera " seductively " sings , " Show a little leg / You gotta shimmy your chest " . The uptempo number " Show Me How You Burlesque " has a " modern sounding " dance production , but " lack of melody and strong hooks " . The power ballad " Bound to You " , co @-@ written by Sia Furler , has the same musical style to " You Lost Me " which was also co @-@ written by Furler from Bionic , features Aguilera 's strong vocal delivery .
