After recently sharing the cover art and release date for her seventh studio album, This Is Acting, Australian singer-songwriter Sia gives us “Bird Set Free." This new power ballad serves as the second single on the album after “Alive,” which she released last month. Both songs were co-written and intended for Adele, and Sia recently said that she will be featured on Adele’s new album 25. According to Sia, the new album is set to feature certain songs that were originally written for artists like Rihanna and Beyoncé, saying that she’s “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." This Is Acting is slated to release on January 29, but in the meantime, enjoy the two singles below.
