Hot music? (6)
I believe the answer is:
piping
'hot music?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'hot music?' is the wordplay.
I cannot really understand how this works, but
'hot' could be 'in' (both can mean fashionable) and 'in' is located in the answer.
'music?' could be 'g' and 'g' is present in the answer.
The remaining letters 'pip' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for piping that I've seen before include "Descriptive of very hot food" , "The playing" , "really hot" , "Tube; very hot" , "Lengths of tube" .)
