Reporter of latest music captivating hearts (9)
I believe the answer is:
newshound
'reporter' is the definition.
(I've seen this in another clue)
'latest music captivating hearts' is the wordplay.
'latest' becomes 'new'.
'music' becomes 'sound' (I am not sure about this - if you are sure you should believe this answer much more).
'captivating' means one lot of letters goes inside another (inserted letters are captured or captivated).
'hearts' becomes 'h' (abbreviation used in card games e.g. bridge).
'sound' enclosing 'h' is 'shound'.
'new'+'shound'='NEWSHOUND'
'of' is the link.
Can you help me to learn more?
(Other definitions for newshound that I've seen before include "read this person's reports?" , "American journalist" , "Paper reporter" , "He's after a story" , "assiduous seeker of stories" .)
