... judge album by Queen (8)
I believe the answer is:
recorder
'judge' is the definition.
(historical type of judge)
'album by queen' is the wordplay.
'album' becomes 'record album' (synonyms).
'by queen' becomes 'er' (short for Elizabeth Regina ie Queen Elizabeth. I am not sure about the 'by' bit.).
'record'+'er'='RECORDER'
Can you help me to learn more?
(Other definitions for recorder that I've seen before include "Maybe video" , "Fipple-flute" , "A kind of flute or note-taker" , "One taking down notes" , "sound device" .)
