In an interview for Billboard, Sia said, "She [Aguilera] was just excited to get to work with the artists she loves. There's this misconception that she's a middle-America kind of person. But she's a little hipster. You go back to her house and sit by the fire with some wine, and what's playing over the sound system? The Knife and Arthur Russell. She doesn't listen to pop music". In the standard edition of Bionic, the couple co-wrote three tracks, including "You Lost Me". The song was described as "the heart of the album" by Aguilera.
