Sia's new album This Is Acting is comprised entirely of songs the singer wrote for other artists. The album's first single, "Alive," was written with Adele for the British singer's record-breaking new album 25 but was rejected at the last moment. Sia told Zane Lowe in a recent interview that her new album will feature songs she wrote for high profile stars including Rihanna and Beyoncé. Today, Sia dropped her newest song off the album titled "Bird Set Free," another soaring pop cut. 

Sia also created an Instagram account for her new album where she revealed the album's cover art. Listen to the new track above and look for This Is Acting to drop Jan. 29, 2016.
