Hear Sia’s New Song With Kanye West, ‘Reaper’

“Chandelier” star Sia has written a lot of hits for a lot of pop diva—so many, in fact, that her new album is made up entirely of songs passed on by the likes Rihanna and Adele. Yet there’s perhaps no more curiosity-piquing collaboration than the one she just announced: Kanye West. The rapper is one of several name-brand hitmakers on the notoriously shy singer’s upcoming record This Is Acting, due Jan. 29, and Sia has just shared the full version of the song he co-wrote and co-produced, “Reaper,” after teasing it earlier in the week.
