Carly Rae Jepsen owes a lot to Justin Bieber, but it's truly her charm and infectious Robyn-esque ear for pop melody that keeps us coming back. "I Really Like You" is no "Call Me Maybe," but its saccharine message of crushin'—and crushin' hard—is just as universal. It helps that the tune is impossible to listen to just once. Seriously. We dare you! —Maria Sherman

Yes, Ariana's breathy coos lure you in, but the intricate production from the rising Norwegian DJ gives the hazy song all kinds of playback potential. Listen for everything from booming 808s and trappy snares to lazer beam zaps and cowbells. —Jeff Benjamin

After revealing five (!) buzz singles ahead of the release of third album Froot, Marina & The Diamonds finally dropped the record that came chocked with seven more delicious new songs. We haven't stopped getting life from the self-affirming anthem "Can't Pin Me Down," and we're just dying to shout the words at a hater or an ex. (The fuzzy rock-pop stomper also boasts some of the best lyrics from the album.) —Jeff Benjamin

Fans agree that Kelly Clarkson's sixth studio album Piece by Piece is her strongest collection in years, with loads of feel-good, pop gems. We're keen on "Nostalgic" with those oh-so-throwback '80s synths and power chords. —Jeff Benjamin

Kacey Musgraves flirts with the line between country and pop unlike any other. She first came into our field of vision with the fun-loving equality anthem "Follow Your Arrow," then returned with the equally great "Biscuits." This deliciously divine tune possesses one of the best lyrics of the year, hands down: "Mind your own biscuits and life will be gravy." Yes ma'am! —Maria Sherman

As Rihanna's new music looks poised to move beyond past trend-hopping pop diva, this ballad —off the original soundtrack to the Rihanna-starring animated kids flick Home—showcases Ms. Fenty's voice like we've never heard. It's probably her best vocal performance to date, and it's got us crazy excited to see more of her evolved vox on her upcoming eighth album. —Jeff Benjamin

We're all heartbroken over the news about Zayn leaving One Direction, no doubt, but luckily EXO is satiating all our boy band needs and then some. The 10-member K-pop troupe returned with their genre-hopping new single "Call Me Baby," sounding like something 'N Sync would release if their prime had hit in 2015. —Jeff Benjamin

Don't let the title trick you—"Dead" is a lush and dreamy piece of pop by this must-watch green-haired singer. The lyrics are brutally candid, hitting a very particular breed of humbleness: "When things are good, I don't believe that they're for real." She explained the track's meaning to Noisey, saying: 

"Sometimes I get so overwhelmed with how fortunate I am and with my friends, how good we have it—when everything is going so great and so wonderfully. For some reason, I have this negative reaction, like, 'I don't deserve any of this and I have to be dead right now. This has to be a dream.' I had come up with song title ideas and I thought 'Dead' was an interesting title if we could spin it in a positive way."

Complex and dreamy? We love it. —Jeff Benjamin

Maroon 5's "Sugar" is already one of the biggest singles of the year and with good reason—who doesn't love a tune that can possibly result in Adam Levine showing up at your wedding? The Nicki Minaj remix only serves to better the tune, adding a very real, very cool edginess. —Maria Sherman

Most music fans know they can count on Kylie Minogue for pristine pop perfection, but less know that her younger sister Dannii is also just as a dependable of a diva. Nearly eight years after releasing her album Club Disco—which included the disco-pop jewel "He's the Greatest Dancer"—the little Minogue is back with a shimmering new dance anthem. "Summer of Love" is an undeniably campy and crafted specifically for the clubs, but it gives good indication of Dannii's new direction, which sounds very exciting. —Jeff Benjamin

Now is the time for new Grimes. The alt-pop phenom first shared new last year with "Go," a song she originally penned for Rihanna. Apparently the "Bitch Better Have My Money" star wasn't into it...boo! Now Grimes has shared a new demo with "Realiti," a tune that most likely won't show up on her upcoming album but remains great nonetheless. If it's any indication of her upcoming release, Grimy's keeping the quality high. —Maria Sherman
