If you've been wondering how Taylor Swift managed to write and record "Christmas Tree Farm" in less than a week, wonder no more! On December 23, Swift shared a behind-the-scenes video documenting the creation of the song. "So the idea I have for the song is 'Christmas Tree Farm' 'cause I grew up on one," she explains in the five-minute clip. "It's about how, like, you're in the city and you're stressed out and your life is feeling really low but in your heart is a Christmas tree farm!" She goes on to show her studio session with producer Jimmy Napes, plus footage of a 10-piece gospel choir recording background harmonies. Cut to a few days later, and Swift declares, "Hi. We're done with the song. It's done now. We're gonna put it out. We hope you like our Christmas song. Merry Christmas!"
