Taylor Swift's "I Knew It, I Knew You" Reaches No. 1 on Radio Songs Chart

Taylor Swift's latest single, "I Knew It, I Knew You," has captured the top spot on Billboard's Radio Songs chart, marking her ninth career No. 1 on this significant airplay ranking. This achievement places her among the artists with the most rulers of all time on the chart.

While Swift frequently graces the top of various Billboard charts, her dominance on the Radio Songs chart is particularly noteworthy. "I Knew It, I Knew You," a standalone single created for the animated film Toy Story 5, has now reached the pinnacle after previously holding the second position.

Taylor Swift Returns to the Radio Chart Summit

The track "I Knew It, I Knew You" has climbed from No. 2 to the coveted No. 1 position on the Radio Songs chart this week. This chart measures the songs that reach the largest total audience across all U.S. radio formats. Swift's ascent means she has swapped places with Bruno Mars, whose song "Risk It All" has now moved to second place.

Swift Secures Her Ninth Radio Chart No. 1

With "I Knew It, I Knew You," Taylor Swift notches her ninth No. 1 on the Radio Songs chart, and it's her first chart-topper in nearly three years. Her previous No. 1 on this chart was "Cruel Summer," which experienced a resurgence years after its initial release, partly due to its inclusion in The Eras Tour setlist.

Here are all of Taylor Swift's No. 1 hits on Billboard's Radio Songs chart:

"Anti-Hero"
"Bad Blood" featuring Kendrick Lamar
"Blank Space"
"Cruel Summer"
"I Knew It, I Knew You"
"I Knew You Were Trouble."
"Shake It Off"
"Wildest Dreams"
"You Belong with Me"

Singles from "The Life of a Showgirl" Did Not Reach No. 1 on Radio

Interestingly, none of the singles promoted from Swift's 2025 album The Life of a Showgirl managed to reach the No. 1 position on the Radio Songs chart. The lead single, "The Fate of Ophelia," came closest, peaking at No. 2. Other singles from the album, such as "Opalite" and "Elizabeth Taylor," also saw strong chart performance but did not reach the top spot.

Taylor Swift Ranks Fourth All-Time Among All Artists

While this latest No. 1 strengthens Swift's position, she remains fourth on the all-time list of artists with the most Radio Songs No. 1s. Rihanna continues to lead with 13 chart-toppers, followed by Bruno Mars with 12, and Mariah Carey with 11. Swift's nine No. 1s put her ahead of artists like Usher, Katy Perry, and Maroon 5, who each have seven.

"I Knew It, I Knew You" is a Multi-Chart Success

"I Knew It, I Knew You" has demonstrated significant success across multiple Billboard charts. It has already reached No. 1 on the Billboard Hot 100, the Streaming Songs chart, the Digital Song Sales chart, and the Billboard Global 200. The single also made a strong impact on country charts and previously topped the Adult Pop Airplay chart before its current No. 1 on the general Radio Songs tally.
