<P> 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 . </P> <P> The two songs performed by Cher are: "Welcome to Burlesque" and "You Haven't Seen the Last of Me". "Welcome to Burlesque" was described as "a' Cabaret' - style oompah that shows both skill and humor". The power ballad "You Haven't Seen the Last of Me" features Cher's powerful vocals . </P> <P> In August 2010, a video containing a scene from the film featuring Aguilera performing "Something's Got a Hold on Me" was released onto YouTube .
