With just over a week until the release of her new album This Is Acting, Sia on Wednesday night shared a brash new cut titled "Unstoppable."
It's definitely a brazen offering from the forthcoming record, which is a collection of songs Sia originally penned for other singers, such as Rihanna, Adele and Beyoncé.
While This Is Acting arrives on Jan. 29, "Unstoppable" is available now as an instant download along with five other tracks for those who pre-order the album.
