Already a star in his native UK, Conor Maynard has targeted America in his quest for world domination. A discovery and protégé of Ne-Yo, Maynard bypasses fluffy pop for assertive R&B streaked with EDM on Contrast. “Animal,” “Vegas Girl,” and “Can’t Say No” have a libidinous YOLO undertow reminiscent of when Justin Timberlake brought sexy back. “Glass Girl” has a confessional quality familiar to fans of Frank Ocean. And on “Lift Off,” producer Pharrell can barely contain his giddiness for this sweet-looking English kid with pipes.
