Taylor Swift's 'I Knew It, I Knew You' Sets Record, Dominates Movie Songs Chart for Fourth Month

Taylor Swift’s hit song “I Knew It, I Knew You” has extended its impressive run at the top of Billboard’s Top Movie Songs chart, powered by Tunefind (a Songtradr company). The track, featured in the highly anticipated “Toy Story 5,” secured its fourth consecutive month at No. 1, maintaining its dominance through September 2026.

The rankings for the Top Movie Songs chart are meticulously determined using a formula that blends song and film data provided by Tunefind with sales and streaming information tracked by Luminate. This comprehensive approach ensures that the chart accurately reflects public interest, generally including newly released films from the preceding three months, though exceptions are made for movies whose music continues to garner significant attention.

“I Knew It, I Knew You” made its debut on June 5, 2026, ahead of “Toy Story 5’s” theatrical premiere on June 19. Its chart success was immediate and widespread; beyond ruling the June, July, and August 2026 Top Movie Songs lists, it also premiered at No. 1 on the weekly Billboard Hot 100 chart dated June 20, where it held the top position for two weeks. In September 2026, the song remained a strong performer, spending the entire month within the Hot 100’s top 10, including three weeks at No. 3. During this period, Luminate reported that “I Knew It, I Knew You” garnered an impressive 40.5 million official streams and sold 7,000 downloads in the United States.

Joining Swift on the September 2026 chart, similar to the August edition, were multiple tracks from “Spider-Man: Brand New Day.” Leading these entries was Tame Impala’s “Loser,” which climbed to No. 2. The superhero film, released on July 31, fueled significant gains in streaming, sales, and even radio play for several of its featured songs. “Loser” proved to be the biggest beneficiary, reaching a new peak of No. 18 on the Hot 100 dated August 29 and remaining in the survey’s top 25 throughout September 2026. In September alone, “Loser” achieved 43.6 million streams and 3,000 downloads. Other notable “Spider-Man” synchs included Steve Lacy’s “Oh Yeah?” at No. 4 (37.8 million streams, 1,000 downloads) and Bad Bunny’s “EoO” at No. 6 (22.7 million streams, 1,000 downloads).

Making the biggest splash from a newly released movie was “Practical Magic 2,” the much-anticipated sequel to the 1998 cult classic, which premiered on September 10. The film placed two tracks on the latest Top Movie Songs chart: Fleetwood Mac’s iconic “Landslide” at No. 3 (27.5 million streams, 3,000 downloads) and King Harvest’s “Dancing in the Moonlight” at No. 8 (12.4 million streams, 1,000 downloads).
