Swift performed the track live at the Toy Story 5 world premiere at the Dolby Theatre and during a career retrospective at the Grammy Museum.
Background and development
By September2025, Swift had been approached about writing an original song for Disney and Pixar's animated film Toy Story 5. Swift was initially uninterested, prompting Jessica Choi, one of the film's producers, to write her a letter outlining Toy Story 5 female-focused approach. Choi argued that Swift's involvement was necessary because of her career in a "male dominated industry" and her use of music to address that experience. In February2026, when her schedule permitted, Swift requested to see Toy Story 5. After attending an early advance screening of the film, she immediately conceived the song "I Knew It, I Knew You" and wrote it upon returning home.
Swift wrote and produced "I Knew It, I Knew You" with her longtime collaborator Jack Antonoff; it was written, produced, and recorded within eight hours after the screening. A longtime fan of the Toy Story franchise, Swift said that the song was inspired by the story of the character Jessie across the Toy Story films and that she had wanted to write music for the franchise's characters since watching Toy Story (1995) at the age of five. Swift and Antonoff are the only musicians to write music for the Toy Story franchise besides Randy Newman, who endorsed their contribution.
The writer-director of Toy Story 5, Andrew Stanton, stated that upon his first listen, he felt that the song fit within the franchise like a "long-lost family member". According to the film's visual effects supervisor Thomas Jordan, only a "very small group" knew about "I Knew It, I Knew You" before the week of its announcement, and Pixar created a "decoy version" of Toy Story 5 without the song for press and unaware crew members. Tom Hanks, who voices the character Woody, said that the cast was unaware of Swift's involvement until hours before the announcement.
Production and composition Music "I Knew It, I Knew You" incorporates 14 musical instruments: acoustic guitar, bass guitar, electric guitar, piano, percussion, strings, drum kit, banjo, mandolin, harmonica, saxophone, celesta, Hammond organ, and Mellotron. Antonoff played nine of them, with further contributions from his Bleachers bandmates Michael Riddleberger, Sean Hutchinson, Mikey Freedom Hart, Evan Smith, and Zem Audu, and from Bobby Hawk. The song was recorded by Antonoff, Laura Sisk, Oli Jacobs, and Jack Manning at Electric Lady Studios in New York City and Tamarind Studios in Los Angeles. Sisk mixed it at Sharp Sonics Studios (Los Angeles), while Ruairí O'Flaherty mastered it at Sterling Sound Studios (Los Angeles).
"I Knew It, I Knew You" is 2minutes and 58seconds long. It is an upbeat country and country-pop ballad set to a midtempo rhythm. The track features pop and indie elements, a blues- and folk-influenced bassline, and a retro soul-style horn arrangement. It incorporates Americana-style harmonica trills and elements of folk-rock in the opening; banjos, saxophones, and "Beach Boys-style harmonies" after the second refrain; and a key change in the bridge. According to Swift, the composition was informed by Newman's distinctive chord progressions and musical sensibilities. Her vocals feature a slight twang, a "soft, staccato insistence", and a tentative whisper in the lyric "all you said was: 'Hi.... The track includes "billowing" background vocals, credited to Swift, Antonoff, and Sam Dew. The song's acoustic version combines classical instrumentation—including harpsichord, mandolin, harmonica, celesta, and Hammond organ—with a "modern twang", while the piano rendition adopts a slower, more balladic production.
Journalists described the track as a return to country music for Swift. Bryan West of USA Today wrote that it recalled her songs "The Best Day" (2008), "Betty", and "Dorothea" (both 2020). Consequence Liz Shannon Miller likened its steady bassline to Squeeze's single "Tempted" (1981), and its country twang to Swift's albums Taylor Swift (2006) and Folklore (2020), as well as her song "The Bolter" (2024). Neil McCormick of The Daily Telegraph described it as having a "1970s soft pop rock" quality reminiscent of Carole Bayer Sager and Neil Sedaka. The Guardian Laura Snapes identified the rising chords accompanying the lyric "life has ways of leaving those days behind" as a new melodic gesture for Swift.
Lyrics
Written from Jessie's perspective, "I Knew It, I Knew You" explores themes of friendship, memories, and reconnection. The lyrics employ a country-style songwriting and address the return of a loved one whom the narrator had thought lost or out of contact. The unexpected reunion prompts bittersweet memories and emotions and reaffirms the love between them. The lyrics portray the highs and lows of their relationship over time and include imagery-filled reflections referencing first love and summer days. The narrator reflects on the past in the first verse, and the second verse expands on that reflection with the lines "I watched you drive around the bend/ For what I thought would be the last time I saw my friend/ But love has ways of bringing things back to life". Swift stated that several lyrics were written with double meanings, citing the opening lines, "I knew you through the daze of the blades of the grass in summer/ Parachutes for the free fall of being younger": "daze" evokes the blurred quality of childhood memories, as well as "days" phonetically; "blades of grass" recalls childhood play while reflecting the toys' small stature; and "parachutes" refers both to the army toys in Toy Story and to a protective figure during childhood.
The lyrics hint at Jessie's progression and a new beginning for her with a loved one. Some journalists interpreted "I Knew It, I Knew You" as an answer song to another Toy Story track, "When She Loved Me", reading the narrative as a reunion between Jessie and her former owner Emily. The Guardian Laura Snapes described the song as a "moment of gentle elation" in which Jessie recognizes Emily after years apart and remembers details about her, adding that Swift's singing "trembles with a trace of anxiety at how precarious even that deep love can be." Journalists observed that, like other Toy Story songs, the lyrics are told from a toy's point of view but are not explicitly confined to the toy-human relationship; they can be read as a reunion with an estranged friend, a romantic partner, or someone from childhood. Melodic Magazine Sofia Treviño wrote that "I Knew It, I Knew You" contained a "sense of child-like wonder" and a "carefree tone" that recalled Swift's album Fearless (2008).
Release and promotion On April30,2026, Swift's official website briefly displayed a 48-hour countdown with a sky-blue background and white clouds, resembling imagery associated with the Toy Story franchise. It was removed after approximately ten minutes and expired without an announcement. That same day, Swift's official fan engagement team shared a cloud-themed post on social media. On May29, Disney/Pixar billboards for Toy Story 5 displaying the initials "TS" against cloud imagery appeared in cities worldwide, and the cover artwork for Swift's album 1989 (Taylor's Version) (2023) was altered on streaming platforms, replacing the seagulls in the background with five clouds. The following day, Pixar posted a video of Jessie dancing on top of the "TS" billboard, accompanied by a caption that references Swift's single "Shake It Off" (2014).
Further promotions included the cover artwork for Swift's album 1989 (2014) being updated with a Toy Story-style font; cloud imagery illuminating the Empire State Building; clouds appearing in TikTok searches for Swift's name; and her "essentials" playlist on Apple Music being updated to feature only the fifth tracks from her albums, with every "T" and "S" in the lyrics capitalized. A new countdown appeared on Swift's website and on billboards in New York City and Los Angeles on June1; the website version was accompanied by an illustration of a house and barn, with Jessie appearing in the scene and the "TS" billboard placed on a hill beneath a cloudy sky. When the countdown ended at 14:00Eastern Daylight Time (UTC−04:00), "I Knew It, I Knew You" was announced as an original song by Swift for Toy Story 5, along with its release date.
