For most of “Blurred Lines,” Robin Thicke convincingly conjures ’70s-era R&B and disco, sounding like Barry White penned Michael Jackson’s “Off the Wall.” The album’s chart-topping title track revises the sonic party of Marvin Gaye’s “Got to Give It Up” (with Pharrell and T.I.), while tracks “Ooo La La,” “Get in My Way” and “Ain’t No Hat 4 That” (co-written by Thicke’s actor father, Alan) sound like Studio 54 fare. “Take It Easy on Me” strikes a more current electro-soul path, and the Dr. Luke and Cirkut-produced “Give It 2 U” (featuring Kendrick Lamar) boasts an insistent energy and pointed language that fit closer to contemporary styles. The falsetto-flaunting Thicke slows down only during “For the Rest of My Life.”
