Series produced by pop star about the origin of reggaeton (6)
I believe the answer is:
string
'series' is the definition.
(sequence of similar items or events)
'pop star about the origin of reggaeton' is the wordplay.
'pop star' becomes 'Sting' (front-man of The Police).
'about' is an insertion indicator.
'the origin of' indicates taking the first letters.
The initial letter of 'reggaeton' is 'r'.
'sting' enclosing 'r' is 'STRING'.
'produced by' is the link.
(Other definitions for string that I've seen before include "Thin length of cord etc" , "It's difficult to know how long a piece of it is" , "Suspend" , "Violin wire/catgut" , "Series of events" .)
