During the mid-1970s, highly slick and commercial bands such as Philly soul group The O'Jays and blue-eyed soul group Hall & Oates achieved mainstream success. By the end of the 1970s, most music genres, including soul, had been disco-influenced. With the introduction of influences from electro music and funk in the late 1970s and early 1980s, soul music became less raw and more slickly produced, resulting in a genre of music that was once again called "R&B", usually distinguished from the earlier rhythm and blues by identifying it as "contemporary R&B".
