Taylor Swift's 'I Knew It, I Knew You' Debuts at No. 1 on Hot 100

Taylor Swift wrote the song 'I Knew It, I Knew You' for the end credits of Toy Story 5. The song debuted at No. 1 on the Billboard Hot 100. Randy Newman had written the original music for the Toy Story franchise since it began in 1995.

On Sunday (Nov. 1), Swift sat for a Q&A with director Andrew Stanton after a special screening of Toy Story 5. Stanton said that Swift was the only person he had in mind to follow in Newman's footsteps. Swift finished the song with Jack Antonoff in the studio on the same day she saw an early screening.

Swift performed the song with Newman at the film's Hollywood premiere. The song has garnered significant Oscar buzz for best original song at next year's awards. Swift's Oscar campaign included special performances at the Academy Museum Gala in mid-October and at a Grammys Icon Session in August.

Swift's brother, Austin Swift, was the first to bring Toy Story 5 to her attention. Swift said her brother does all her music synchs. Swift said the film's characters Bonnie and Blaze helped her relate to Toy Story 5. Swift said she moved to Nashville when she was 14 and met a girl named Abigail there.

As of November 2, 2026, the album The Life of a Showgirl: The Encore by Taylor Swift is number 8 on the Apple Music US albums chart.
