Dancehall is a type of reggae which developed in the early 1980s. The style is characterized by a DJ singing and rapping or toasting over raw and danceable reggae music (riddims). Many of the lyrics in the early dancehall were crude and "slack", though in the late 1990s, this changed as many artists converted to Rastafarianism and changed their lyrical focus. Various varieties of dancehall achieved some crossover success outside of Jamaica during the mid- to late-1990s.
