Taylor Swift shared a video on her social accounts Friday captioned “The making of Midnights,” referring to the title of her upcoming album. The clip splices together footage from various recording sessions, mostly closeups of Swift in the studio. One of them shows her bouncing along with Jack Antonoff, confirming that he’s involved in the album — no surprise there considering Antonoff has worked on every LP she’s released since 1989 way back in 2015. The more interesting aspect of the teaser is its soundtrack.
