On his English-language debut, Latin superstar Prince Royce aims to prove himself the crossover heir to Ricky Martin and Enrique Iglesias. The Bronx-born singer, 26, pulls out all the stops, enlisting an army of producers and guests like Snoop Dogg, Pitbull and Jennifer Lopez. But Double Vision lacks focus, failing to establish a clear identity for Royce: He morphs from a version of Jason Derulo (the title track) to Drake (“Dangerous”) to Bruno Mars (“Extraordinary”). His voice is malleable enough, but he stands out most when he goes back to his roots. “There for You” floats along a tropical, guitar-laced groove, and “Lucky One” is all bachata sweetness, guaranteed to make the girls swoon.
