Taylor Swift had to fight to contribute to One Chance soundtrack

Country star Taylor Swift defied her music managers' advice not to contribute a new song to the One Chance movie soundtrack after falling in love with the real-life underdog story.

The film stars actor James Corden as cell phone salesman Paul Potts, who shot to fame as an opera singer after winning Simon Cowell's reality TV show Britain's Got Talent in 2007.

Swift reveals she was on a recording break when she heard about the soundtrack opportunity, and she had to fight her representatives to break her radio silence and create the song Sweeter Than Fiction.

She says, "I had to fight to do this because I try to take a break in between albums and try to give people a minute to not hear me on the radio.

"I had to go around and ask people, 'Can I please, please put something out even though we're supposed to be going quiet?' My management, my label were like, 'No new music until the next album comes out.' Then I saw the movie and I was like, 'I have to be a part of this.'"

Swift teamed up with fun. guitarist Jack Antonoff to pen the upbeat track and they had no trouble coming up with ideas for the tune.

She adds, "Getting to see the struggles and triumphs of someone who never stopped chasing what he was after really inspired me. It's a beautiful movie and I just wanted to share it with as many people as I could."
