Nine songs topped the chart in 2025, with "Ordinary" by Alex Warren spending the most weeks atop the chart at 17 weeks, and "APT." by Rosé and Bruno Mars achieving the first number one of the year, reclaiming the top spot after spending seven weeks at number one in 2024.
Five artists, Lola Young, Doechii, Alex Warren, Huntrix (Rei Ami, Ejae, Audrey Nuna) and Olivia Dean, reached the top for the first time. Kendrick Lamar achieved his first solo number one with "Not Like Us", having previously reached the top as a featured artist on Taylor Swift's "Bad Blood" in 2015.
