This week, “I Knew It, I Knew You” becomes the 15th Billboard Hot 100 No. 1 of Taylor Swift‘s illustrious pop career — and the 10th from this decade alone. But it also marks a first for Swift: It’s the only one of her 15 No. 1s to come from a movie soundtrack.

Swift has a long track record of notable movie songs, including a pair of No. 2-peaking Hot 100 smashes with 2010’s “Today Was a Fairytale” (from Valentine’s Day) and 2016’s “I Don’t Wanna Live Forever” alongside ZAYN (from Fifty Shades Darker). But it’s the Jack Antonoff-co-written/co-produced “I Knew It,” from the upcoming Toy Story 5, which becomes her first to get over the top on the chart — while also becoming the former Nashville hitmaker’s first song in over a decade to be embraced by country radio.
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 below.
