Sia "Unstoppable"

Sia 'Unstoppable'
As the release of Sia's This Is Acting quickly approaches, the pop star has shared another cut off the upcoming album.
We've already heard "Bird Set Free," "Alive," "One Million Bullets" and the Kanye-featuring "Reaper."
This time, it's a track called "Unstoppable," and it features all the radio-friendly bombast we've come to expect from a Sia single. It's a declaration of courage and confidence, and you can give it a listen in the player below.

This Is Acting is out on January 29 through RCA.
