Taylor Swift's new song for the upcoming film "Toy Story 5," titled "I Knew It, I Knew You," has been released with an accompanying music video, now available on streaming platforms like Spotify and Apple Music.

This release has led to significant streaming milestones for the artist.

The song's music video features footage related to the character Jessie, a key figure in the "Toy Story" franchise.

Following its release, "I Knew It, I Knew You" became the most-streamed country song in a single day by a female artist in Spotify history.

This achievement is partly attributed to the music video's exclusive availability on these streaming platforms, drawing fans to contribute to the record.

Additionally, the track secured the biggest first 24-hour streaming debut globally for any song on Amazon Music in 2026, further cementing its immediate impact.

Swift reportedly wrote the song immediately after an early screening of "Toy Story 5," and it is described as a return to her country music roots, reminiscent of her earlier albums.

The song was co-written with frequent collaborator Jack Antonoff.

The music video opens with Jessie meeting Woody, with Bullseye in the background, and includes scenes of Jessie joining other toys like Buzz Lightyear.

It also features flashbacks to Jessie's past, including her previous owner leaving her, and concludes with a young, red-headed girl playing with the cowgirl doll, with some of this footage appearing to be from the fifth film.

The song's release positions Taylor Swift as a potential contender for an Oscar nomination in the Best Original Song category.

She has previously contributed songs to films such as "Where the Crawdads Sing," "Cats," and "The Hunger Games." While it is not yet confirmed if Swift will have a voice role in "Toy Story 5," a connection has been noted through Greta Lee, who voices Lilypad in the film and appeared in Swift's music video for "Opalite." Swift announced her involvement with the film on June 1, and the song is now widely available on all music streaming platforms.
