Overview
- Swift, who posted a behind‑the‑scenes studio clip on Thursday, says she watched an early screening at 11 a.m., then wrote, produced and recorded the end‑credits song that same evening in about eight hours.
- The song, titled “I Knew It, I Knew You,” was co‑written and co‑produced with Jack Antonoff and was inspired by the Toy Story character Jessie.
- “I Knew It, I Knew You” debuted at No. 1 on the Billboard Hot 100 and set platform‑specific first‑day streaming, sales and radio milestones across Apple Music, Spotify and other services.
- Disney and Pixar kept Swift’s involvement secret during production by using a decoy version of the film for many screenings, a tactic that amplified surprise when the track and its music video were revealed.
- The rapid creation, high streaming numbers and the controlled rollout have increased the soundtrack’s visibility and could bolster the film’s box office and awards momentum in the months ahead.
