Taylor Swift has reached another historic milestone. ✨

This week, “I Knew It, I Knew You” debuts at No. 1 on the Billboard Hot 100, becoming the 15th chart-topper of her career and her 10th No. 1 of the 2020s. The achievement also marks a first for Swift: It’s the first No. 1 hit of her career to come from a movie soundtrack. The song appears on the upcoming 'Toy Story 5' soundtrack and was co-written and co-produced with longtime collaborator Jack Antonoff. How long do we think the hit will last? And do we think it presages a full country pivot from Taylor? Billboard staffers discuss these questions and more: billboard.com/music/pop/tayl…
