Stealing hearts, music genre's poetic and lyrical (9)
I believe the answer is:
rhapsodic
'lyrical' is the definition.
(thesaurus)
'stealing hearts music genre's poetic' is the wordplay.
'stealing' is an insertion indicator.
'hearts' becomes 'h' (abbreviation used in card games e.g. bridge).
'music' becomes 'rap' (musical genre).
'genre's poetic' becomes 'sodic' (I can't justify this - if you can you should give a lot more credence to this answer).
'h' placed into 'rap' is 'rhap'.
'rhap'+'sodic'='RHAPSODIC'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for rhapsodic that I've seen before include "Expressing ecstatic feeling" , "Expressing delight" , "of utter delight" , "Freely emotional" , "Wildly emotional" .)
