Analyst finds article first about style of music (9)
I believe the answer is:
therapist
'analyst' is the definition.
(thesaurus)
'article first about style of music' is the wordplay.
'article first' becomes 'theist' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' indicates putting letters inside.
'style of music' becomes 'rap' (I've seen this before).
'theist' placed around 'rap' is 'THERAPIST'.
'finds' acts as a link.
Can you help me to learn more?
(Other definitions for therapist that I've seen before include "Provider of relieving 57 Across" , "See 21" , "Shrink" , "Help" , "provider of treatment" .)
