Australian superstar Sia released her new song "To Be Human" on May 25. U.K. act Labrinth features on the "Wonder Woman" soundtrack cut.

"To Be Human" will be featured in the upcoming superhero movie "Wonder Woman" starring Gal Gadot. Sia has been keeping busy on the soundtrack front, having released "Helium" for "50 Shades Darker" and "Never Give Up" for "Lion" earlier this year. Labrinth from Noah Cyrus' "Make Me (Cry)" joins Sia on "Human."

"To Be Human" was written by Florence + the Machine's Florence Welch and Lana Del Rey producer Rick Nowels. Strings and sweeping synths back Sia grappling with Wonder Woman learning to live in the civilian world. "To be human is to love even when it gets too much / I'm not ready to give up," she sings. Sia's superhuman vocals meet their match with Labrinth's heavenly voice supporting hers. "Human" is an epic theme song elevated to otherworldly levels thanks to Sia and Labrinth.

"To Be Human" featuring Labrinth is now available on iTunes and Apple Music. "Wonder Woman" opens in theaters on June 2.
