inauthentic, cynical, "slickly commercial", and formulaic form of entertainment. In contrast, rock music is often heralded as an authentic, sincere, and anti-commercial form of music, which emphasizes songwriting by the singers and bands, instrumental virtuosity, and a "real connection with the audience". Simon Frith's analysis of the history of popular music from the 1950s to the 1980s has been criticized by B. J. Moore-Gilbert, who argues that Frith and other scholars have overemphasized the role of rock in the history of popular music by naming every new genre using the "rock" suffix. Thus when a folk-oriented style of music developed in the 1960s, Frith termed it "folk rock", and the pop-infused styles of the 1970s were called "pop rock". Moore-Gilbert claims that this approach unfairly puts rock at the apex and makes every other influence become an add-on to the central core of rock. In Christgau's Record Guide: Rock Albums of the Seventies (1981), Robert Christgau discussed the term "pop-rock" in the context of popular music's fragmentation along stylistic lines in the 1970s; he regarded "pop-rock" as a "monolith" that "straddled" all burgeoning movements and subgenres in the popular and semipopular music marketplace at the time, including singer-songwriter music, art rock, heavy metal, boogie, country rock, jazz fusion, funk, disco, urban contemporary, and new wave, but not punk rock.
