There's a new song from Taylor Swift out there, but it's not a single. From upcoming British film One Chance, the movie's about "an opera-singing sensation after he wins Britain’s Got Talent in 2007." Taylor's song, however, has nothing to do with the movie's inspiration Paul Potts — it's more John Hughes than Pavarotti — with fun. guitarist and Lena Dunham beau Jack Antonoff co-writing. The Brat Pack all just got goosebumps.
