One appreciates some reggae's the technique (8)
I believe the answer is:
aesthete
'one appreciates' is the definition.
(someone who appreciates art)
'some reggae's the technique' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'AESTHETE' can be found hidden inside 'reggaes the technique'.
(Other definitions for aesthete that I've seen before include "One is particularly appreciative of beauty" , "Person with great sensitivity towards the arts and the beautiful" , "Someone who claims sensibility for art and nature" , "person of culture" , "Person with great appreciation of the beautiful" .)
