Sia's new album is comprised of numerous tunes that were rejected by major pop stars.
The 39-year-old Australian songstress, who is behind hits like Chandelier, wrote a tune called Alive with Adele for the British singer's forthcoming LP.
However, Adele didn't want the song, which led Sia to repurpose the track.
'We wrote three songs in two days and none of them made the cut, and [Alive] was one of them,' she revealed to Ryan Seacrest during an interview on his radio programme. 'I said to her, 'Do you mind if I pitch it to, let's say, Rihanna?' She said, 'Yeah, but can you take my vocal off it because I don't want my vocal floating around out there on a demo.' And I was like, 'Sure.' So I went and recut the vocal and everybody in my life was like, 'You can't give this away to anybody.'
