Sia has shared the full-length version of "Reaper," her collaborative track with Kanye West.

The Australian singer and songwriter’s new song will appear on This is Acting, the tracklist for which she has revealed in a flurry of thematic tweets. 

Sia: The Billboard Cover Story

West co-wrote and co-produced "Reaper," which Sia originally penned for Rihanna’s album ANTi. “Reaper,” like all the songs on This is Acting, was scrapped by the artist it was intended for.

“You came to take me away/ So close I was to heaven's gates/ But no baby, no baby, not today,” she sings on it.  

Sia has downplayed the significance of "Reaper," which she explained she wrote on her own with “notes” from Kanye.

“I don't care about the song,” she told Rolling Stone. “I know in print that will look bad, but what I mean is I'm not emotionally attached to it. I thought it was a fun song. I think it's a good, fun song, but I didn't anticipate it being on the record. But my manager really likes it so I put it on for him.”

Sia Reveals 'This Is Acting' Release Date

In recent months, Sia has shared new tracks "Alive," "Bird Set Free” and "One Million Bullets,” all of which appear on her seventh studio album, due out Jan. 29. 

Sia drip-fed the tracklist Wednesday with snaps of theater marquees from around the globe, each emblazoned with the title of a song. It's the follow-up to 1000 Forms Of Fear, which debuted at No. 1 in the U.S. and Australia following its release in July 2014.
