KAROL G combines the melodic instincts of a pop singer with flows as tight as anyone on hip-hop radio. She became one of reggaetón's breakout stars of the late ‘10s by bringing this mixture to some of the most forward-thinking beats of any genre. On “Mi Cama”, she sings over tough dembow drums and a deliriously looping hook that's part EDM and part Jersey club. “Pineapple” is filled with even more twists: While Karol keeps her voice cool and soft, the beat moves forward like a sonic Rube Goldberg device, with each sound effect—chimes, handclaps, vibraphone—somehow triggering the next.
