Crossover music

Crossover is a term applied to musical works or performers appearing on two or more of the record charts which track differing musical tastes, or genres. If the second chart combines genres, such as a "Hot 100" list, the work is not a crossover.

In some contexts the term "crossover" can have negative connotations associated with cultural appropriation, implying the dilution of a music's distinctive qualities to appeal to mass tastes. For example, in the early years of rock and roll, many songs originally recorded by African-American musicians were re-recorded by white artists such as Pat Boone in a more toned-down style, often with changed lyrics, that lacked the hard edge of the original versions. These covers were popular with a much broader audience.

In practice crossover frequently results from the appearance of the music in question in a film soundtrack. For instance, Sacred Harp music experienced a spurt of crossover popularity as a result of its appearance in the 2003 film Cold Mountain, and bluegrass music experienced a revival due to the reception of 2000's O Brother, Where Art Thou?. Even atonal music, which tends to be less popular among classical enthusiasts, has a kind of crossover niche, since it is widely used in film-making and television production scores "to depict an approaching menace", as noted by Charles Rosen.
