The song "Hey Goldmember" interpolates and is a parody of four '70s disco songs formed into a medley; "Sing a Song" by Earth, Wind & Fire, "Get Down Tonight", "(Shake, Shake, Shake) Shake Your Booty", and "That's the Way (I Like It)", all by KC and the Sunshine Band.
"Sing a Song" is not listed in the credits but is sung by Beyoncé at the beginning.
