The "Billboard" Hot 100 is a chart that ranks the best-performing songs in the United States. Its data is compiled by Luminate Data and published by American music magazine "Billboard". The chart is based on each song's weekly physical and digital sales collectively, the amount of airplay impressions it receives on American radio stations, and its audio and video streams on online digital music platforms.
"Not Like Us" (2024) by Kendrick Lamar returned to the top spot for a third week in 2025, following his Super Bowl LIX halftime show on February 9, becoming the first non-holiday song (second after Mariah Carey's 1994 "All I Want for Christmas Is You") to top the chart three separate times with breaks of two or more months in between each domination. The following week, Lamar became the 15th act to replace himself at number one, with the SZA duet "Luther" (2024). With thirteen weeks atop the chart, it became the longest-running number-one single of the year, the 46th song to peak at number one for at least ten weeks, and the longest-running number one for both Lamar and SZA.
As of the chart dated July 5, ten artists have charted at number one in 2025, with two ― Tate McRae and Alex Warren ― reaching the top spot for the first time. Lamar is the only artist to chart two number-one songs this year so far.
The first half of the year was marked by little to no movement in the charts, with a huge number of songs having been released the previous year, making 2025 one of the most stagnant years for pop music so far.
