Talk about a summertime sure thing. Nineteen-year-old Dominican Kat Deluna is prepped to combust with a platinum-plated debut so certain you can practically smell the smoke emanating from its juicy one-spin hook and manic tempo. Accompanied by dancehall staple Elephant Man, aka the Energy God, and reggaetón queen Ivy Queen, the bilingual crossover beauty—who grew up in poverty in the Dominican Republic and the Bronx before studying music at the New Jersey School of Performing Arts—combines Caribbean cadence with a novel mesh of hip-hip, R&B and merengue, as she offers a simple call to "Hold me tight to your body/Whine your body up." Deluna's launch single offers ultimate seasonal sizzle—over the airwaves, on the beach, down the highway and across dancefloors. A "Whine" to be heard loud and proud the world over. Look for full-length "9 Lives" in August. —Chuck Taylor
