Sia is continuing to release tracks from her upcoming album, This Is Acting, and the latest is a real power anthem.

Titled "Unstoppable," the new track finds the singer declaring, "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."

Last year, Sia released the upcoming album's first single, "Alive," that shared a similar empowering sentiment.

This Is Acting, which will be released on January 29, consists of songs that Sia actually wrote for other artists. When the other singers ultimately turned the tunes down, Sia decided to take them for herself.

She hasn't revealed which artist "Unstoppable" was originally penned for, but she certainly has made it all her own.
