Relive Taylor Swift And Jack Antonoff's Friendship Over the Years

In an August episode for Time's "Person of the Week" podcast, Antonoff looked back on his friendship with Swift. "She's the first person who recognized me as a producer," he said of the "Anti-Hero"s singer. "A lot of people are afraid to sign off on something that isn't done by a proven person. I had written lots of songs and produced them, but they would always sort of go somewhere else. So the label or whoever could say, oh, we had this person produce it. And, you know, I put my heart and soul into that song and she said, 'I love it.'"
