Sia Gives Us New Song, 'Unstoppable,' To Punch Things To

'I'm a Porsche with no brakes/ I'm invincible,' Sia sings on your new empowerment jam.

Maybe we're not always at our strongest, but with Sia's new song, "Unstoppable," she's teaching us how to fake it.

The empowering track is the sixth one we've heard off her album of pop-star rejects, This Is Acting, and it encourages those who are feeling weak to put their armor on. The song seems like it's taking the message from her previously released track, "Alive," and giving it a boost. Instead of just surviving, she's going to prove to people that she's going to succeed, and she's going to look good doing it.

"I'm unstoppable/ I'm a Porsche with no brakes/ I'm invincible," Sia sings on the fierce "Unstoppable." "Yeah, I win every single game/ I'm so powerful/ I don't need batteries to play/ I'm so confident, yeah, I'm unstoppable today."
