Taylor Swift released the original single “I Knew It, I Knew You” for Pixar’s upcoming Toy Story 5 on Friday, June 5, 2026. Within 24 hours the track shattered streaming records on Spotify, Apple Music and Amazon Music, and it topped the iTunes Top Songs chart while amassing more than 300,000 YouTube views in the first four hours after midnight.

On Spotify, the single became the most‑streamed country song in a single day by a female artist in the platform’s history. The figure was confirmed by Spotify’s own data release, which noted that the track’s first‑day play count surpassed all previous female‑artist country singles on the service.

Apple Music announced that the song also became the biggest country single of 2026 on its platform and set a new all‑time record for the largest first‑day play count among soundtrack singles. Apple Music’s statement highlighted that the track’s debut surpassed the previous record held by any soundtrack song released in the past decade.

Amazon Music reported that the single logged the biggest 24‑hour global streaming debut of any song on its platform this year. In addition, the track reached No. 1 on the iTunes Top Songs chart and drew more than 300,000 views on YouTube within four hours of its midnight release.

“I Knew It, I Knew You” was written and produced by Swift in collaboration with longtime partner Jack Antonoff. The harmonica‑and‑banjo‑infused country track was inspired by Jessie, the cowgirl character who appears in Toy Story 5. The song celebrates reunion rather than loss, offering a tonal contrast to Sarah McLachlan’s “When She Loved Me” from Toy Story 2.

In a statement issued through The Walt Disney Company, director Andrew Stanton praised Swift’s contribution: “It’s incredible just how meaningful it’s been having Taylor write and perform this song. Her connection to Jessie and the immediate way she understood what the character was going through was undeniable. The song is so deeply connected to Toy Story. So much so that on first listen, it instantly felt like it had always belonged there, like a long‑lost family member.”

Joan Cusack, who voices Jessie since Toy Story 2, also spoke to the song. She told USA Today that it “is such a good song” and that she was “so glad that it resonated with her and she wanted to write a song for it, because it means so many more people come to see the movie.”

Swift shared her thoughts on Instagram after the release. She wrote that “writing this song felt like a musical departure and coming home at the same time. Creating something for Jessie was a new challenge and also felt like second nature all at once. And being a Toy Story kid from the age of 5 til now … is an adventure I plan to be on, to infinity and beyond.”

The single is part of the Toy Story 5 soundtrack, which will be released on June 19, 2026, the same day the film debuts in U.S. theaters. The soundtrack, produced by Walt Disney Records, also features original compositions by Randy Newman. The record‑breaking performance of Swift’s track underscores the continued commercial viability of cross‑genre collaborations between pop artists and major film franchises.

At present, the song’s streaming success has positioned it as a leading promotional asset for the upcoming film. No additional singles have been announced, but the soundtrack’s release date remains set for June 19. The record‑setting debut also highlights the growing importance of streaming metrics in measuring a film’s pre‑release buzz and the strategic use of high‑profile artists to drive audience interest.

The current situation is that “I Knew It, I Knew You” remains the most‑streamed country single of the day on Spotify, Apple Music’s top country track of 2026, and Amazon Music’s highest‑debuting song of the year. The track’s performance will likely influence marketing strategies for the Toy Story 5 launch and may set a new benchmark for future soundtrack releases.
