Taylor Swift wrote and recorded a song for the end credits of Toy Story 5, with reports indicating she completed the task in just eight hours. The song is titled "I Knew It, I Knew You" and was created after Swift saw the movie, with some outlets suggesting she was inspired by what is referred to as "songwriter zoomies". The exact details of the song's creation are not entirely clear, but it is reported to have been a rapid and possibly hectic process.
