Taylor Swift and former One Direction member Zayn Malik have just treated their fans with a surprise new song for the soundtrack to Fifty Shades Darker. I Don’t Wanna Live Forever is the name of this tune which unexpectedly appeared in the US iTunes Store just before midnight and reaching #1 within an hour of its release! Two huge pop stars joined forces to deliver a passionate duet, a mid-tempo pop tune on which Zayn's falsetto dominates the chorus. Both stars have a huge fanbase so I expect this song to be a hit! This is the first single from the Fifty Shades Darker soundtrack, which is due to drop Feb. 10 through Republic Records. The song was written specifically for the feature film by Swift, Jack Antonoff & Sam Dew and produced by Antonoff.
