A lack of quiet song refrain in rock (8)
I believe the answer is:
shortage
'a lack of' is the definition.
(I've seen this before)
'quiet song refrain in rock' is the wordplay.
'quiet song' becomes 'sh' (I can't justify this - if you can you should believe this answer much more).
'refrain' becomes 'tag' (I've seen this before).
'in' indicates putting letters inside.
'rock' becomes 'ore' (ores are found in rocks).
'tag' placed into 'ore' is 'ortage'.
'sh'+'ortage'='SHORTAGE'
Can you help me to learn more?
(Other definitions for shortage that I've seen before include "may put price up" , "Her goats (anag)" , "famine" , "Deficit" , "Need" .)
