Murder music is a term coined by British gay rights activist Peter Tatchell in the mid-1990s to describe the homophobic work of certain Jamaican musicians, primarily dancehall and ragga artists who called for and encouraged physical violence and murder of homosexuals. The Stop Murder Music campaign is jointly run by Outrage!, the Black Gay Men's Advisory Group, and Jamaican gay rights organization Jamaica Forum of Lesbians, All-Sexuals and Gays (J-Flag).
