People — music genre (4)
I believe the answer is:
folk
I believe this clue is a double definition.
'people' is the first definition.
(informal term for people)
'music genre' is the second definition.
(I've seen this in another clue)
(Other definitions for folk that I've seen before include "Kind of music" , "[KINDRED]" , "People; type of music" , "Sort of music" , "People in general" .)
