Taylor Swift Wrote and Recorded 'Toy Story 5' Song Just Hours After Seeing Movie: 'Got the Songwriter Zoomies' | Video

Taylor Swift was so inspired after seeing "Toy Story 5" in a preview screening that she wrote and recorded its end credits song in the same day. The Grammy winner recounted "one of the most fun days of my life" in a new video posted to social media Thursday, sharing that after seeing the Disney-Pixar sequel at 11 a.m., she "got the songwriter zoomies" and jet off for a day of writing and recording for the rest of the day. The product? "I Knew It, I Knew You," which debuted ahead of Friday's "Toy Story 5" premiere at No. 1 on the Billboard Hot 100. Watch the video, . . .
