Sia gifted fans with her first-ever holiday album appears under the tree.
The new track follows the first release from Everyday Is Christmas, the jazzy "Santa's Coming for Us."
Sia describes how she and producer Greg Kurstin ended up writing the all-original 10-song album in an interview with Zane Lowe: "I thought we had a bit of a shortage of good Christmas music. There's obviously the classics and stuff, but anything new, I wasn't vibing that much on it," she said.
"I just was having so much fun, because it's already there, all of the concepts, you just have to expand on them. It's not like you have to have an original idea to begin with. It's like, Christmas, mistletoe, ho-ho-ho, Santa Claus, Christmas list, elves. You've got all of the subject matter," she explained.
"It was easy and fun. So, we did it in two weeks. And I couldn't stop writing new songs -- so, I ended up with an original album by accident."
Everyday Is Christmas is scheduled to arrive Nov. 17.
