Reggae [SEP] Criticism of dancehall and ragga lyrics
Some dancehall and ragga artists have been criticised for homophobia, including threats of violence. Buju Banton's song "Boom Bye-Bye" states that gays "haffi dead". Other notable dancehall artists who have been accused of homophobia include Elephant Man, Bounty Killer and Beenie Man. The controversy surrounding anti-gay lyrics has led to the cancellation of UK tours by Beenie Man and Sizzla. Toronto, Canada has also seen the cancellation of concerts due to artists such as Elephant Man and Sizzla refusing to conform to similar censorship pressures. After lobbying from the Stop Murder Music coalition, the dancehall music industry agreed in 2005 to stop releasing songs that promote hatred and violence against gay people.
