Surfer Blood

"Demon Dance" (3:16)

Producer: Gil Norton

Writer: Surfer Blood

Publishers: Various

Warner Bros./Kanine Records

From a lyrical perspective, Surfer Blood's latest indie shout-along is the band's darkest, headiest moment to date, and a powerful reintroduction. "Demon Dance" leads new album "Pythons" with pounding tom-toms and paint-peeling distortion that veers the group's sound toward straight-faced classic rock. -RR

Folk

Matt Hires

"Restless Heart" (3:21)

Producer: Espionage

Writers: Matt Hires, Alex Dezen, Espen Lind, Amund Bjorklun

Publishers: Another Wayfaring Stranger/Pasa Songs/Stellar Songs/EMI Blackwood (BMI)

Atlantic Records

This baby-faced singer/songwriter's latest single opens in a Celtic-acoustic rumble: "Pretty girls come from the ugliest places," Hires sings, quivering diary-ripped poetry over strums and drums as the track careens toward a fist-pumping chorus. The cut offers an ultra-polished variation on the Americana-tinged folk-pop now dominating radio, and following the success of Mumford & Sons and the Lumineers, Hires is smartly banking on a commercial breakthrough here. -RR

Hip-Hop

Ace Hood featuring Future & Rick Ross

"Bugatti" (4:30)

Producer: Mike WiLL Made It

Writers: Various

Publishers: Various

We the Best/Young Money/Cash Money/Republic

Mike WiLL Made It provides a menacing backdrop on Ace Hood's latest banger, wherein the tax bracket of the young hustler shifts six notches. Future's Auto-Tuned hook explodes when he declares that he "woke up in a new Bugatti," while Ross completes the power play as he and his cohorts contemplate life in the fast lane. -KI

Latin

Carlos Vives featuring Michel Telo

"Come le Gusta a Tu Cuerpo" (3:50)

Producers: Andres Castro, Carlos Vives

Writers: Carlos Vives, Andres Castro

Publisher: Sony Music Publishing (BMI)

Gaira/WK/Sony Music Latin

Vives poses the question "How does your body like it?" as he and Telo demonstrate a certain pluckiness in embracing this romantic melody. Vives endlessly fantasizes about the object of his affection, and while the metaphors run a little rampant (including one involving a tiger), the track, co-produced by Andres Castro, draws the listener in with hand claps and cymbals. -KI

Pop

Michael Buble‰

"It's a Beautiful Day" (3:20)

Producer: Bob Rock

Writers: Michael Buble, Alan Change, Amy Foster

Publishers: Various

Reprise/Warner Bros.

Taylor Swift's "We Are Never Ever Getting Back Together" just got some competition in the race for the most joyful breakup single of the past year. "It's a Beautiful Day" showcases all of Buble's usual tricks, with big-band orchestration and style dripping from every syllable, but lyrics like "When you said goodbye/My whole world shines" turn this "Beautiful Day" into a playful kiss-off. -JL
