"We were hanging out at her house in Rhode Island," says Antonoff, "and we were talking about John Hughes movies, and a lot of the music that inspired [them], and just this general culture of sound in that time period that was really larger-than-life in an anthemic, positive way. These songs could be at the end of films that were really, really beautiful and said a lot."
The friendship blossomed into a collaboration when Antonoff sent Swift a track that he had been working on, and she begged him to send the demo her way. "That actually ended up being a song called 'I Wish You Would' which is going to be on her album," he says. "We first worked on that song together and realized we kind of have a good thing, and the next thing we did was 'Sweeter Than Fiction' which was on the ['One Chance'] soundtrack, and after that we did 'Out Of The Woods' and another song called 'You Were In Love.' So 'Out Of The Woods' was the third thing we worked on together, and probably the easiest. I sent her the track for it, and she sent back a voice note with the verse and chorus in what felt like five seconds. And it was just perfect. It's eery how similar it is to what the final product is."
