Sia – “Unstoppable”

We’re a week away from the release of This Is Acting, the collection of songs that Sia originally wrote for other artists but then ended up using herself. We’ve already heard a ton of its songs: “Alive,” “Bird Set Free,” “One Million Bullets,” “Cheap Thrills,” and the Kanye West collab “Reaper.” She’s now shared yet another one, a swollen self-esteem anthem called “Unstoppable.” If I had to guess, I’d say she wrote it with someone like Katy Perry in mind — though, in Sia’s hands, it comes out sounding more like Florence + The Machine. Listen to it below.

This Is Acting is out 1/29 on RCA.
