“Unstoppable” is the fifth track on Sia’s 2016 album This Is Acting. It has been called a “stomping, empowering jam” and “swollen self-esteem anthem of her “, with lyrics like, “I’m unstoppable, I’m a Porsche with no brakes / I’m invincible, 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.” The song was written by Sia, Christopher Braide, and produced by Jesse Shatkin.
“Unstoppable” has received mostly positive critical reception, with most reviewers commenting on its theme of empowerment. Jessie Morris of Complex commented that the song sounds like a “page torn right out of Demi Lovato‘s Confident book”, while editors of other media platforms like Idolator noticed this as well, which raised speculation that the track was intentionally written for Lovato.
Michelle Lulic of Bustle said its lyrics “make it clear is the female empowerment anthem you had no idea you were missing from your life. Seriously, if you need a song to get you through the rest of the work week… and this is the song you’ve been waiting for.” C.C
