With only weeks to go until the release of her new album This Is Acting, Sia has shared a buoyant new track "Reaper," which she co-wrote with Kanye West, who also co-produced the song.

As we previously mentioned, the album's title stems from the fact that all the songs were previously intended for other stars, including the likes of Beyoncé, Rihanna and Adele.

Hear "Reaper" below, ahead of the Jan. 29 release of the full album.
