John Legend's brand of classy, soulful and politically-engaged music filled a niche on the contemporary R&B scene, beginning with his critically successful debut album Get Lifted (2004). The album marked the first time that mainstream music lovers heard Legend's smooth vocals bringing a certain suavity to hip-hop soul, most notably in the hit single "Ordinary People." Legend's sophomore release, Once Again (2006), exceeded the commercial and critical success that he enjoyed with his first album. Instead of shooting for a blend of soul, pop, and hip-hop as he did in his first release, the Grammy Award-winning singer headed for a more innovative, adult contemporary direction on Once Again, which featured the catchy mid-tempo "Save Room" and the rock-laced song "Stereo." Legend showcased his political convictions and maturing sound on albums such as Wake Up! (2010), a collaboration with hip-hop group The Roots and a solid effort from an undeniably versatile musician and vocal powerhouse.
