Taylor Swift released an original song titled "I Knew It, I Knew You" on Friday, June 5, 2026, for the upcoming film Toy Story 5 [1], [2].

The collaboration marks a high-profile intersection between the world's largest pop star and Pixar's most successful franchise. By contributing a thematic piece to the soundtrack, Swift leverages her massive fan base to amplify the promotional cycle for the upcoming movie.

The song was released globally via streaming platforms and social media [1], [3]. Swift said the track was inspired by the journey of the character Jessie. She said the process was a musical departure and coming home at the same time [4], [5].

Industry data indicates the song became an immediate commercial success. Hugh McIntyre of Forbes said the track led the iTunes chart at the beginning of the tracking period [6]. This rapid ascent to the number one spot reflects the immediate market impact of Swift's brand on digital sales [6].

While the song is now available to the public, the specific placement of the track within the film has not been detailed. Gizmodo said many of the people who made the latest Pixar film only recently found out that Swift contributed the song [7]. This suggests the collaboration may have been kept under tight wraps during the production phase to maximize the impact of the announcement.

The release follows a pattern of Swift expanding her reach into cinematic storytelling. The song's focus on Jessie's character arc aligns with the emotional core of the Toy Story series, exploring themes of loyalty and identity, while allowing Swift to experiment with a different sonic palette than her recent studio albums [4].

"It felt like a musical departure and coming home at the same time"

For Swift, the project allows her to maintain cultural ubiquity through a family-friendly medium, ensuring her music reaches audiences beyond traditional pop listeners while continuing her trend of diversifying her creative portfolio through film and storytelling.
