Music rocks on beat that can be hot (8)
I believe the answer is:
capsicum
'music rocks on beat that can be hot' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'music rocks on beat' is the wordplay.
'rocks' indicates an anagram.
'on' indicates putting letters inside (as in clothing \'on\' a person).
'beat' becomes 'cap' ().
'music' with letters rearranged gives 'sicum'.
'sicum' placed around 'cap' is 'CAPSICUM'.
Can you help me to learn more?
(Other definitions for capsicum that I've seen before include "hot stuff perhaps" , "Pepper fruit" , "Eg, chilli pepper" , "Pepper plant" , "Chili pepper genus" .)
