Wayne Smith's "Under Mi Sleng Teng", produced by King Jammy in 1985 on a Casio MT-40 synthesizer, is a seminal ragga song. "Sleng Teng" boosted Jammy's popularity immensely, and other producers quickly released their own versions of the riddim, accompanied by dozens of different vocalists.^{[citation needed]}

Ragga originated in Jamaica during the 1980s, at the same time that electronic dance music's popularity was increasing globally. Ragga spread to Europe, North America, and Africa, eventually spreading to Japan, India, and the rest of the world. Ragga heavily influenced early jungle music, and also spawned the syncretistic bhangragga style when fused with bhangra. In the 1990s, ragga and breakcore music fused, creating a style known as raggacore.

The term "raggamuffin" is an intentional misspelling of "ragamuffin", a word that entered the Jamaican Patois lexicon after the British Empire colonized Jamaica in the 17th century.^{[citation needed]} Despite the British colonialists' pejorative application of the term, Jamaican youth appropriated it as an ingroup designation. The term "raggamuffin music" describes the music of Jamaica's "ghetto dwellers".
