Taylor Swift released a new original song titled "I Knew It, I Knew You" for the Toy Story 5 soundtrack on June 5, 2026 [1].

The track marks a significant return to the artist's country-roots sound and further cements her dominance on the global music charts. By bridging the gap between a major cinematic franchise and her early musical style, Swift continues to expand her commercial reach across different demographics.

Speaking on the set of Good Morning America, Swift discussed the creative process behind the song with longtime collaborator Jack Antonoff. She said she wrote the track after seeing the movie, describing a feeling of "songwriter zoomies" that prompted her to create and record the song on the same day.

The single has already achieved massive commercial success. It debuted at No. 1 [2] on the Billboard Hot 100 for the chart week of June 20, 2026 [3]. This achievement brings Swift's total number of No. 1 hits on the Hot 100 to 15 [4].

Swift's decision to utilize a country-inspired sound for the Pixar project reflects a deliberate choice to align the music with the emotional themes of the film. The collaboration with Antonoff ensured the track maintained a polished production, while honoring the acoustic elements of her early career.

The success of the song serves as a primary promotional pillar for the Toy Story 5 release. With the track capturing the top spot on the charts, the synergy between the film's marketing and Swift's fan base provides a significant boost to the movie's visibility before its wide release.

"I Knew It, I Knew You" debuted at No. 1 on the Billboard Hot 100.

This chart-topping debut reinforces Taylor Swift's unique ability to monetize nostalgia and cross-genre appeal. By returning to a country sound for a family-oriented franchise like Toy Story, she secures a wider listener base while extending her record-breaking streak on the Billboard Hot 100, further distancing herself from other artists in terms of historical chart dominance.
