The thing about the yearly quest to name an “official” song of the summer is that it’s usually over it before it begins—most of the winning songs are released well before memorial day, and most hit No. 1 on the charts by mid-June. History also tells us that songs with the word “summer” in them never live up to their titles’ ambitions, otherwise we’d all be taking about Maroon 5 right now instead of the likes of Fetty Wap or Wiz Khalifa.
Demi Lovato does not seem to care about those odds with her new single “Cool for the Summer,” and it’s pretty clear why after one listen: Lovato’s sultry vocals and producer Max Martin’s Midas touch melt the track’s air-conditioned synths into a sweltering, rock-infused banger. Martin is on a roll this summer (is he ever not?) with Taylor Swift’s “Bad Blood” remix, Adam Lambert’s “Ghost Town” and the Weeknd’s “Can’t Feel My Face,” but if there’s anything we learned from Katy Perry in the summer of 2008, it’s that the kind of bi-curiosity Lovato seems to be singing about won’t hurt her chances of success, either. Consider this the season’s dark horse.
Years & Years, “King”
The British trio’s electro-pop stunner has gone to No. 1 in several countries but barely cracked U.S. Top 40. That’s America’s loss: “King” is as compulsively danceable as any ‘90s house anthem, and frontman Olly Alexander’s bewitching voice gives it plenty of heart to match.

Florence + the Machine, “Delilah”
There are so many things that Florence + the Machine do well: big sound, soaring vocals and lyrics that paint epic dramas. “Delilah,” from the latest album How Big, How Blue, How Beautiful, combines all of those elements beautifully in one exuberant track, with the added bonus of a swelling, multi-tracked call-and-response.

St. Vincent, “Bad Believer”
It speaks to St. Vincent’s talent that a bonus track appended to a re-release of last year’s self-titled opus—TIME’s second-best album of the year—is as good as anything else that has come out in 2015. It’s also not surprising: the herky-jerky fuzz of “Bad Believer” is one more reason to worship her.

Major Lazer featuring MØ and DJ Snake, “Lean On”
The Danish singer who showed you new corners of your iPhone keyboard makes up for last year’s Iggy Azalea misfire “Beg For It” with this tropic thumper that leans on “Turn Down for What” mastermind DJ Snake for some extra oomph—no special characters needed.

Kacey Musgraves, “Biscuits”
Since shaking up the country scene with 2013’s Same Trailer Different Park, Kacey Musgraves has breathed new life into Nashville with songs that employ a pure country sound while making jabs at traditional southern values. “Biscuits” may not send up any overtly political messages, but its lazy-river, banjo-laden melody melds satisfyingly with its age-old message: live and let live.

Tobias Jesso Jr., “How Could You Babe”
The 29-year-old didn’t take up the piano with any seriousness until he was just about ready to call his music career quits after struggling to make it as a songwriter in Los Angeles. Thank goodness he did—this ballad from his March debut album Goon time-warps back to the 1970s with flashes of McCartney.

Janelle Monáe featuring Jidenna, “Yoga”
Only an artist as visionary as Janelle Monáe could turn an ancient Indian tradition into a sex metaphor that redefines “downward dog” and makes a statement about not letting society police your individuality. It’s definitely not Vinyasa, but it’s got plenty of flow.

Galantis, “Peanut Butter Jelly”
This song’s got everything: clapping hands, bull horns and your favorite childhood sandwich (assuming you didn’t draw the short stick in the allergy game). Infused with retro vibes care of 1960s soul singer Bettye Swann, “Peanut Butter Jelly” is arguably the best song of the year to dance to, work out to or justify the transformation of your car into a rush-hour disco for one.
—Eliza Berman
Tanlines, “Pieces”
In a parallel universe, this glistening synth-pop gem was the real windows-down song of the summer. Though it set a high bar the rest of the duo’s second full-length, Highlights, couldn’t quite meet, that bassline is as potent as anything that uptown funked you up this year.
—Nolan Feeney
Kendrick Lamar, “The Blacker the Berry”
A complex track by one of the most gifted rappers working today, “The Blacker the Berry” is angry, rough and urgent — and performed with lacerating precision.
—Megan Gibson
Tink, “Ratchet Commandments”
The protege of hip-hop heavyweight Timbaland is neither the next Aaliyah nor the next Missy Elliott nor anyone other than just Tink—and that’s more than enough on this humorous call for her peers to rethink their priorities. Yes, it’s a little slut-shaming, but with five mixtapes by age 20, Tink’s earned the right to scoff at your work ethic.

Jamie xx, “I Know There’s Gonna Be (Good Times)”
In this strong contender for Song of the Summer, British DJ Jamie xx mixes a soul sample (The Persuasions’ “Good Times”) with synths that sound like steel drums, adding some welcome vocals from Atlanta rapper Young Thug and Jamaican dancehall artist Popcaan into a breezy, feel-good track.
—Megan Gibson
Carly Rae Jepsen, “All That”
The “Call Me Maybe” singer turned heads by working with über-hip producers Ariel Rechtshaid and Dev Hynes, but the way her syrupy-sweet vocals gently rock this would-be ‘80s prom song shows why music’s coolest names take her calls.
–Nolan Feeney
Rihanna, “FourFiveSeconds”
It’s perhaps the most delightful song ever made about being stuck at work on a Tuesday. Rihanna broke her long (for her, at least) hiatus with a country-inflected collaboration with Kanye West and Paul McCartney, all about being on the edge of a nervous breakdown after dealing with people all day. Relatable stuff: No wonder the trio’s performance at the Grammys this year was the night’s most crowdpleasing singalong.
