Caribbean music (6)
I believe the answer is:
reggae
'caribbean music' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for reggae that I've seen before include "Popular music of Jamaican origin" , "Bob Marley's music" , "W.I. music" , "Type of West Indian music" , "Jamaican musical style" .)
