Which singer contributed Toy Story 5's original single I Knew It, I Knew You?

Taylor Swift contributed the original Toy Story 5 single “I Knew It, I Knew You.”

The song was created specifically for the film and was inspired by Jessie, the cowgirl toy whose story has long supplied some of the franchise’s most emotional moments. Swift’s connection to the project also drew attention because she has spoken about growing up with Toy Story and admiring its characters. The collaboration links her songwriting persona with one of Pixar’s most recognizable worlds.

“I Knew It, I Knew You” is not a Randy Newman song from the original Toy Story score. Newman returned to compose the film’s instrumental score, while Swift supplied the separately promoted original single. That difference explains why several music-related names can appear in coverage of the film without having the same role.

The song also carries a country influence associated with Swift’s early musical identity and with Jessie’s western styling. Its title and subject connect naturally to the franchise’s recurring themes of friendship, loyalty, memory, and change. The singer credited for the single is therefore Taylor Swift, not Ariana Grande, Dua Lipa, or Billie Eilish.
