Sia will release her next album This Is Acting on Jan. 26, and on Wednesday she debuted “Unstoppable,” another track from the collection.

Like the previously released tracks, the song was originally written for another artist, but is a stomping, empowering jam with lyrics like, “I’m unstoppable, I’m a Porsche with no brakes / I’m invincible, I win every single day / I’m so powerful I don’t need batteries today / I’m so confident that I’m unstoppable today.”

Sia already released “Alive,” “Cheap Thrills,” “Break Free,” the Kanye West collab “Reaper,” and “One Million Bullets.”

Sia, who’s already mastered the art of songwriting for pop music’s elite, wrote most of the songs on This Is Acting, the follow-up to 2014’s 1000 Forms of Fear, with artists like Rihanna and Adele in mind. “The last album was a little bit of a departure from the albums that came before, so it was transitional,” collaborator Greg Kurstin told EW. “On this, I think anything is game, which is very liberating. There’s a lot of songs on here that we maybe would not have put on the last album.”
