Taylor Swift is using her enormous celebrity platform to broadcast the very moment she heard "I Don't Wanna Live Forever" -- her and Zayn's contribution to the Fifty Shades Darker soundtrack -- on the radio for the first time.

"First time listening to it on the radio, I've never heard it before!" Taylor says before lip-syncing her verse into the selfie-styled camera. Elite squad member Gigi Hadid car-dances in the backseat next to her. The novelty of hearing her song on the radio for the first time has yet to wear off, 10-plus years and five No. 1 singles into her career later!

"I Don't Wanna Live Forever" was officially released in early December. Tay and Zayn appear on the soundtrack alongside Halsey, Tove Lo, John Legend, The-Dream, Nicki Minaj, Nick Jonas, Sia and more. 50 Shades Darker hits theaters on February 10, just in time for Valentine's Day.
