Bruno Mars Breaks Miley Cyrus’ Radio Songs Chart Record

Bruno Mars has reached another milestone on Billboard’s Radio Songs chart as his hit single “I Just Might” extends its reign to a 19th week at No. 1. The achievement moves the track ahead of both the Goo Goo Dolls’ “Iris” and Miley Cyrus’ “Flowers,” making it the fourth-longest-running chart-topper in the history of the ranking.

Released in January 2026 as the lead single from Mars’ album The Romantic, “I Just Might” quickly became one of the year’s biggest hits. The song climbed to No. 1 across several major Billboard charts, including Radio Songs, which measures audience impressions across radio stations throughout the United States. Although Mars later shifted promotional efforts to his second single, “Risk It All,” radio airplay for “I Just Might” has remained exceptionally strong.

With 19 weeks atop the Radio Songs chart in just 24 weeks on the ranking, “I Just Might” now stands alone in fourth place on the all-time list. Before this week’s chart update, the song was tied with the Goo Goo Dolls’ “Iris” and Miley Cyrus’ “Flowers,” each of which previously spent 18 weeks at No. 1. Those two songs now share fifth place among the chart’s longest-running leaders.

Mars still trails three songs that have recorded even longer stays at the summit. The Weeknd’s “Blinding Lights” held the No. 1 position for 26 weeks, a record that was later surpassed by Alex Warren’s “Ordinary” and Shaboozey’s “A Bar Song (Tipsy),” both of which spent 27 weeks atop the Radio Songs chart.

Meanwhile, Mars’ current promotional single, “Risk It All,” has slipped slightly on the latest Radio Songs chart. After reaching a career-high No. 3 last week, the track falls one position to No. 4, allowing “Dracula,” the collaboration between Tame Impala and Blackpink member Jennie, to rise to a new peak at No. 3.

Earlier this year, “I Just Might” also helped Mars achieve another Billboard milestone by becoming his 11th No. 1 on the Radio Songs chart. That accomplishment tied him with Mariah Carey for the second-most chart-toppers in the history of the ranking. Only Rihanna remains ahead, holding the record with 13 No. 1 hits.
