Musical genre captivating eastern capital (5)
I believe the answer is:
seoul
'capital' is the definition.
(Seoul is an example)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for seoul that I've seen before include "Olympic venue" , "Asian capital" , "South Korean capital" , "South Korea capital" , "19 [EASTERN] capital" .)
