Stone fan’s heart fixed to ‘pot’ music style (10)
I believe the answer is:
'style' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I can't see?
'stone fan's heart fixed to pot music' is the wordplay.
I cannot quite see how this works, but
'stone' could be 'rock' (synonyms) and 'rock' is found within the answer.
'music' could be 'b' and 'b' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rockabilly that I've seen before include "Type of music" , "notes of the 1950s" .)
