With Friday's release of the new pscyh-thriller The Neon Demon, the soundtrack includes a contribution from Sia in the form of an elusive, Diplo-produced cut called "Waving Goodbye."

While the rest of the soundtrack is made up of original music from Cliff Martinez, Sia's track offers a haunting detour.

The film stars Elle Fanning, Christina Hendricks and Keanu Reeves.

Listen to "Waving Goodbye" below.
