Raggamuffin music, usually abbreviated as ragga is a sub-genre of dancehall music or reggae, in which the instrumentation primarily consists of electronic music; sampling often serves a prominent role in raggamuffin music as well.Wayne Smith's "Under Me Sleng Teng" was produced by King Jammy in 1985 on a Casio CZ-series synthesizer and is generally recognized as the 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.
