Sia revealed that while she wanted to write music for other artists rather than putting out more albums under her own name, her record contract included one more album. The album's title, This Is Acting, refers to the fact that most of the tracks were intended for other artists.
She recently spoke to NME where she said, "I was planning to be a pop song writer 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 kept all the songs I wanted and had a lot of fun making it."
"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."
Since some of the track were intended for other acts, it's safe to presume that it features at least a few pop and radio friendly tracks. No official release date or track list have been revealed.
