Reggae is a music movement created in Jamaica, contributed to greatly by the late The Hon. Robert Nesta Marley. Reggae is almost like a way of life. And reggae doesn't only involve rastafarians singing about weed. It's about unity, love, and sending that message around the world.
(And now that EVERYONE, that is celebrities, want to jump on the reggae bandwagon, like Sinead O'Connor, Lumidee and Stevie Wonder, the genre has become exploited. Everyone wants to do a collaboration with a reggae star. The Jamaican colours are spread all over, and Jamaica is getting no credit.)
And note, REGGAE is DIFFERENT FROM DANCEHALL MUSIC!! Dancehall is more of a DJ-ing gig and Reggae actually involves singing.
