Sia has admitted that she only released her album '1000 Forms of Fear' last year in a bid to get out of her record contract.
Sia's '1000 Forms of Fear'
The singer hates being in the spotlight and prefers to write for other people, but when she released the LP in 2014 it was well received, but something she only did because it was in the terms of her publishing deal.
Speaking to NME magazine she explained: "Basically, I put this out to get out of my publishing deal.
"I was planning to be a pop songwriter for other artists, but my publishing deal was as an artist, so I had to put one more album out.
"I didn't want to get famous, so I just kept all the songs I wanted and had a lot of fun making it."
Though she only made the record to fulfill obligations, Sia is to release another record called 'This Is Acting', made up of tunes she originally wrote for other people.
"I'm super-productive. I have a full album ready to go and it's much more pop. I'm calling it 'This is Acting' because they are songs I was writing for other people, so I didn't go in thinking, 'This is something I would say'.
"It's more like play-acting. It's fun."
