As of June 21, summer is officially upon us -- though at Billboard, it's already been going on for four weeks now, with the introduction of our official Songs of the Summer listing.
This year, we've already had three different No. 1s: Lady Gaga and Ariana Grande's "Rain on Me," Megan Thee Stallion featuring Beyoncé's "Savage," and DaBaby featuring Roddy Ricch's "Rockstar." That's already two more than we had all of last summer, when Lil Nas X's Billy Ray Cyrus-featuring "Old Town Road" reigned from start to finish. "Rockstar" is on top for a second frame this week, but with 6ix9ine's Nicki Minaj-assisted "Trollz" taking over for it atop the Hot 100, its reign at the Songs of the Summer peak may not be secure for long.
