Every Song on Sia's New Album and the Pop Star Who Was Supposed to Sing It

Sia also talks about "Reaper" in great detail in Rolling Stone. She says, "There's one that I went into a session with Kanye, to write for Rihanna, so that one was intended for her, but then I'm keeping that one." When her interviewer asks if the track in question was "Reaper," she says, "Yeah! . . . I went into the studio to write for Rihanna with Kanye — neither of them showed up — and stayed for less than an hour. They had two tracks. They told me what they had wanted. There were notes from Kanye, and I can't even remember what they were. I remember I just raced in and raced out, and I thought there was something about the chorus that seemed fun about this song, but I never thought it would see the light of day."
