Soul singer's heart broken by a candid and short note (6,8)
I believe the answer is:
aretha franklin
'soul singer's' is the definition.
(I've seen this before)
'heart broken by a candid and short note' is the wordplay.
'broken by' indicates anagramming the letters (a broken form of the letters).
'candid' becomes 'frank' (synonyms).
'and' says to put letters next to each other.
'short note' becomes 'lin' (I can't justify this - if you can you should believe this answer much more).
'heart' with letters rearranged gives 'areth'.
'areth'+'a'+'frank'+'lin'='ARETHA FRANKLIN'
Can you help me to learn more?
(Another definition for aretha franklin that I've seen is " soul singer".)
