Sia usually writes songs for pop divas, but this time she's gifting her musical magic to a movie!
Along with partner Greg Kurstin, gurl wrote and produced the brand new song Opportunity just for Annie!
The song is performed by Quvenzhané Wallis in the movie, and you can see her singing it by the end of the video too!
Ch-ch-check it out (above)!
Annie will be in theaters on Dec. 19th!
