Taylor Swift has added another radio milestone to her career with I Knew It, I Knew You, the original song she created for Toy Story 5.

Billboard says the track climbed two spots to No. 1 on the Pop Airplay chart dated Sept. 26, giving Swift her record-extending 16th No. 1 on the chart. The chart tracks weekly plays across nearly 150 U.S. mainstream Top 40 radio stations.

The latest No. 1 also pushes Swift’s total time at the top of Pop Airplay to a record 52 weeks across her career. Her previous chart leaders include Opalite, The Fate of Ophelia, Cruel Summer, Anti-Hero, Blank Space and Shake It Off.

I Knew It, I Knew You has already performed strongly across several formats. The Toy Story 5 song previously reached No. 1 on the Adult Pop Airplay and Radio Songs charts.

Its success began shortly after its June release, when the track became Swift’s 15th No. 1 on the Hot 100. The song was inspired by Jessie, the cowgirl character from the Toy Story franchise.
