Taylor Swift’s ‘I Knew It, I Knew You,’ from Toy Story 5, hits No. 1 on Billboard’s Radio Songs chart
Taylor Swift is not slowing down. “I Knew It, I Knew You,” her contribution to the Toy Story 5 soundtrack, has climbed to No. 1 on Billboard’s Radio Songs chart, extending one of the most dominant chart runs of her career. The achievement caps a monster rollout for a song that arrived wrapped in mystery and quickly turned into another mainstream juggernaut, proving yet again that a Swift single can conquer nearly every format available to it.
The Radio Songs coronation is the latest peak for a track that has been overachieving since the moment it landed. “I Knew It, I Knew You” debuted at No. 1 on the Billboard Hot 100 upon release, an increasingly rare feat that underscores just how much anticipation surrounded it. Now, by topping Radio Songs, which ranks the most-heard tracks across all US radio formats by audience impressions, the song has proven it has the broad, cross-format appeal that turns a hit into a standard.
An Unlikely Origin at the Movies
Part of what makes the milestone notable is where the song came from. “I Knew It, I Knew You” was written and produced by Swift alongside her longtime collaborator Jack Antonoff for the 2026 animated film Toy Story 5, released through Walt Disney Records. A blockbuster soundtrack cut reaching the summit of Radio Songs speaks both to the enduring pull of the Toy Story franchise and to Swift’s singular ability to make any project she touches feel like an event.
The rollout was pure Swiftian spectacle. Fans first caught wind of something brewing on April 30, 2026, when Swift’s official website briefly displayed a 48-hour countdown set against a sky-blue background with white clouds and blue-outlined yellow numbers, imagery instantly associated with the Toy Story universe. The countdown vanished after about ten minutes and expired without an announcement, sending Swifties into a frenzy. Weeks later, on May 29, Disney and Pixar billboards bearing the initials “TS” against cloud imagery appeared in cities worldwide, confirming the collaboration in the most theatrical way possible.
That kind of teasing has become a Swift signature, and it turns each release into a participatory scavenger hunt for a fanbase that treats every clue as canon. By the time “I Knew It, I Knew You” officially arrived on June 5, the audience was primed, and the song rocketed to the top of multiple charts around the globe.
Another Line in a Record-Breaking Era
The Radio Songs No. 1 slots into a year of almost absurd commercial success for Swift. Her latest album, The Life of a Showgirl, has been rewriting the record books since its release last fall. Its lead single “The Fate of Ophelia” became her longest-running Hot 100 No. 1, and when the follow-up “Opalite” reached the top, it marked the first time since 1989 that Swift had landed two No. 1 singles from the same album.
The album’s impact stretches beyond the singles charts too. The Life of a Showgirl helped push US vinyl sales past $1 billion for the first time since 1983, a staggering commercial marker that reflects Swift’s rare ability to move physical product in a streaming age. “I know that’s a lot of numbers,” she said of the run, “but it all adds up to me being so thankful to the fans who helped make this happen by welcoming this song into your lives with open arms.”
“I Knew It, I Knew You” now adds another trophy to that overflowing case. In a fragmented music landscape where radio, streaming, and sales rarely align behind a single artist, Swift keeps doing the improbable, topping all of them at once. The song is available now via Walt Disney Records.
