The term reggae, in a proper sense, only covers the period in Jamaican
music from 1969 to 1979 (or 1985 depending on opinion).
However in today's vernacular, the term has come to refer to all Jamaican
music from the development of ska in the early 1960s up until today.
It also refers to
music played in the Jamaican reggae styles elsewhere in the world.
Sub-genres and related genres include: Ska, Early or Skinhead Reggae, Roots Reggae, Dub, Nyabinghi Reggae, Lover's Rock, Dancehall, Rumble, Ragga, and Rocksteady.
