Pop rock is a fusion genre characterized by a strong commercial appeal, with more emphasis on professional songwriting and recording craft, and less emphasis on attitude than standard rock music. Originating in the late 1950s as an alternative to normal rock and roll, early pop rock was influenced by the beat, arrangements, and original style of rock and roll. It may be viewed as a distinct genre field rather than music that overlaps with pop and rock. The detractors of pop rock often deride it as a slick, commercial product and less authentic than rock music.

Doo-wop is a subgenre of rhythm and blues music that originated in African-American communities during the 1940s, mainly in the large cities of the United States, including New York, Philadelphia, Pittsburgh, Chicago, Baltimore, Newark, Detroit, Washington, D.C., and Los Angeles. It features vocal group harmony that carries an engaging melodic line to a simple beat with little or no instrumentation. Lyrics are simple, usually about love, sung by a lead vocal over background vocals, and often featuring, in the bridge, a melodramatically heartfelt recitative addressed to the beloved. Harmonic singing of nonsense syllables is a common characteristic of these songs. Gaining popularity in the 1950s, doo-wop was "artistically and commercially viable" until the early 1960s and continued to influence performers in other genres.
