"Sweeter Than Fiction" is a song recorded by American singer-songwriter Taylor Swift for the film One Chance. The song was written and produced by Swift along with Jack Antonoff, best known as the guitarist for indie pop band fun., and was released through Big Machine Records as the lead single from the soundtrack album on October 21, 2013.

One Chance producer Simon Cowell approached Swift with the idea of becoming involved with the project. Swift was reportedly "so moved" by the film's concept she was inspired to write a song for it. The song was co-written by Jack Antonoff, who claims "Sweeter Than Fiction" has a John Hughes vibe, and who tweeted he "[LOVED] working with" Swift.

Swift revealed in an interview with country music blog Taste of Country that she viewed the film as a love story in addition to a chronicling of a man's road to success, and approached the songwriting process from that perspective: "I’m very inspired by the concept of love. And this movie is, in a lot of ways, ... a story of the love his wife … has for him," Swift explained. "That was the story that hit me and really affected me. I wanted to tell a story musically from that perspective."

The song was released to digital retailers as the lead single from the One Chance soundtrack on October 21, 2013. After its release, Swift admitted she had to fight her label to be allowed to release "Sweeter Than Fiction", as she tries to maintain a dormant period between album releases. Big Machine reportedly told Swift "no new music until the next album comes out", but Swift explained that after seeing the film, she insisted "I have to be a part of this."

"Sweeter Than Fiction" is a "rock-tinged"bubblegum pop song that also contains influences of synthpop and new wave music. Critics have deemed the song reminiscent of 80's pop. The song is musically and lyrically upbeat, with Swift singing from the point of view of a longtime friend or fan who has always believed in a performer's talents. "There you'll stand, ten feet tall", Swift sings in the chorus, "and I will say, 'I knew it all along.'" It was written by Swift along with Jack Antonoff and is in the key of B major with Swift's vocal range between the octaves of F Sharp₃ and D Flat₅. It has a tempo of 135 beats per minute and lasts three minutes and fifty-four seconds.
