Bruno Mars' 'I Just Might' has now spent 20 weeks at No. 1 on Billboard's Radio Songs chart

Bruno Mars has now spent 20 weeks at No. 1 on Billboard's Radio Songs chart with "I Just Might," a run that only three songs have ever beaten since the survey started measuring monitored airplay in 1990.

The milestone lands on the charts dated July 11, which cover the June 26 to July 2 tracking week. Billboard's Gary Trust laid out the company Mars is keeping: Alex Warren's "Ordinary" and Shaboozey's "A Bar Song (Tipsy)" share the record at 27 weeks each, The Weeknd's "Blinding Lights" sits at 26, and "I Just Might" is the only other song to reach 20.

The full list is shorter than you'd think

Four songs, and every one of them arrived in the last six years. Radio Songs has been running since 1990. It sat through Mariah Carey, Boyz II Men, Usher's 2004, "Uptown Funk," all of it, and none of that produced a 20-week reign. Programmers used to cycle records out. Now they lock in a hit and leave it there, and the chart has started to look less like a snapshot of what's new and more like a list of what nobody has gotten sick of yet.

What the song actually is

"I Just Might" came out January 9 on Atlantic as the lead single from The Romantic, which followed on February 27. Mars wrote it with Dernst "D'Mile" Emile II, Philip Lawrence and Brody Brown, and produced it with D'Mile. It is a midtempo disco-pop record built on brass, a buzzy bassline and bright rhythm guitar, the same lane Mars has been driving in since "Treasure." Billboard heard Leo Sayer's "You Make Me Feel Like Dancing" in the groove. Pitchfork's Nina Corcoran heard Junior Senior's "Move Your Feet" in the chorus refrain and wrote that Mars "delivers the type of chart-topping boogie that's quintessentially him."

That is the trick of it. The song does not try anything Mars has not already proven he can do, and radio rewarded it for exactly that. It debuted at No. 1 on the Hot 100 in January, his first song to enter at the top, and it has since given him his longest No. 1 runs on Hot R&B Songs (25 weeks and counting) and Hot R&B/Hip-Hop Songs (18 weeks). The Romantic became his second Billboard 200 No. 1 in March, and his first to debut there.

He's also his own competition

Second single "Risk It All" is holding at No. 4 on Radio Songs, its peak. Mars currently occupies two of the top four slots on the chart he is running away with.

Meanwhile the Hot 100 belongs to someone else entirely: Ella Langley's "Choosin' Texas" took a 12th week at No. 1 on the same July 11 rankings. Streaming and radio are telling two different stories about what the summer of 2026 sounds like, and radio's version has a horn section.
