The Evolution of Robin Thicke was supported by two singles; "Wanna Love U Girl" and "Lost Without U". "Wanna Love You Girl" became an urban hit, while "Lost Without U" became a number-one hit on the US Hot R&B/Hip-Hop Songs. The album received generally mixed reviews from music critics but despite that became a sleeper hit. It debuted at number 45 on the US Billboard 200, selling 20,000 copies in its first week,[8] but it later peaked at number five on the chart.[9] In March 2007, the album was certified platinum by the Recording Industry Association of America (RIAA).[10]
