Taylor Swift’s ‘I Knew It, I Knew You’ Debuts at No. 1 on the Hot 100, Making It Her First Movie Soundtrack Song to Reach the Summit

Taylor Swift’s “I Knew It, I Knew You,” the soundtrack single from “Toy Story 5,” debuted at No. 1 on Billboard’s Hot 100, according to a Billboard report published June 16, 2026. The track becomes Swift’s first song from a movie soundtrack to reach the chart’s top position, extending her long-running presence across pop, streaming, and radio metrics tracked by Billboard.

The release also places a major pop star in the center of a high-visibility family film marketing campaign. Billboard characterized the song as a “soundtrack single” tied to “Toy Story 5,” positioning it alongside the franchise’s broader media rollout. The debut to No. 1 reflects the song’s early performance in the same week that Billboard published its report.

Billboard’s writeup framed the achievement in terms of Swift’s catalog and the particular path of movie soundtrack music to the Hot 100. In addition to reaching the summit, the report noted that “I Knew It, I Knew You” is her first movie soundtrack song to top the Hot 100, a distinction that highlights how soundtrack releases often follow different audience patterns than standard album-era singles.

The Hot 100 ranking matters for both music and film business stakeholders because it can drive further attention across streaming services and promotional cycles. A No. 1 debut typically increases visibility for the performer and the credited song, and it can reinforce a studio’s wider strategy for reaching broad audiences, including families and younger listeners targeted by animated feature franchises.

For listeners, the milestone also underscores how quickly major film tie-ins can compete in mainstream music markets. Billboard’s account centers on the song’s chart start and the “Toy Story 5” association, indicating that the track is being treated not only as a soundtrack companion but also as a top-tier singles release within pop distribution channels.
