It was the summer of Drake and Rihanna, who, separately or together, account for an impressive six of the top 20 Songs of the Summer (counting both lead and featured credits). But what song came out on top on Billboard‘s annual recap of the biggest hits from Memorial Day to Labor Day?

Grab a cold drink as we officially count down the top 20 songs of the season.

1 / 20

DJ Khaled, 40, is the oldest lead artist with a song in this year’s top 20 Songs of the Summer recap.

But not by much. The rapper is three weeks older than Sia, whose “Cheap Thrills” ranks #4. This brash, explicit jam was the lead single from the rapper’s ninth studio album, Major Key. (Photo by Kevin Mazur/Getty Images for Anheuser-Busch)

No-19. “Me Too” by Meghan Trainor.

Does this song illustrate a healthy sense of self-esteem or does it depict someone on an ego trip? Visitors to YouTube have been debating that point for months.

No-18. “7 Years” by Lukas Graham.

This philosophical song about the passage of time was a major springtime hit that had enough staying power to carry over into the summer.

No-12. “Just Like Fire” by P!nk.

This robust song, from Alice Through the Looking Glass, was the summer’s second-biggest movie song.

10 / 20

No-11. “Don’t Mind” by Kent Jones.

Click HERE to listen to this song.

This genial hip-hop song could make middle-schoolers excited about learning a foreign language. It’s ultra-catchy and good fun, but it also makes a serious point: “Now I got a lesson that I want to teach/I’m-a show you that where you from don’t matter to me.”

This is from Jones’s 2015 mixtape, Tours. (Photo by Kevin Winter/Getty Images)
