Taylor Swift says she wrote and produced a “Toy Story” song in a single day after seeing “Toy Story 5”

Taylor Swift said she wrote and produced her “Toy Story” song “I Knew It, I Knew You” in a single day, describing the creative process in a brief video she shared on X on Thursday. In the video, Swift told viewers that she saw “Toy Story 5” earlier that morning and then spent the subsequent hours writing and producing the track.

The Hollywood Reporter reported on Swift’s post, which frames the song as the result of an intense, time-compressed session rather than a longer development cycle. Swift also described having “songwriter zoomies,” characterizing the burst of creativity as something that overtook her once she had the morning viewing experience.

According to the account described in the report, Swift’s comments emphasized timing, with the singer stating she wrote and produced the song in the hours immediately after watching the film. The post did not provide additional production details such as session length, studio locations, or contributing musicians within the scope of the reported summary.

The “Toy Story” tie-in adds to the long history of major pop artists being paired with the franchise through original songs connected to specific films. While Swift’s remarks focused on the speed of creation, the report does not specify when the song will be officially released or how it will be used in connection with the film beyond being characterized as a “Toy Story” song.

Swift’s Thursday video comes as major releases and promotional schedules increasingly rely on rapid, social-media-driven updates from artists themselves. In this instance, the singer used a platform video to describe the creative timeline directly to audiences, rather than waiting for a formal label announcement in the report’s summary.

For fans and industry observers, the post also points to the way audience-facing media consumption can feed directly into songwriting and production. Swift’s account ties the track to a specific morning viewing of “Toy Story 5,” describing a chain from watching the film to creating the song the same day, without indicating any longer drafting period.

It remains unclear, based on the report’s summary alone, what elements of the film Swift said she incorporated into the lyrics or sound. The report also does not include information on licensing terms, soundtrack placement, or whether the song will be distributed separately from the film’s soundtrack package.
