Remove ends — did he send you music list? (6)
I believe the answer is:
deduct
'remove' is the definition.
(I've seen this in another clue)
'ends did he send you music list?' is the wordplay.
'ends' suggests the final letters.
The last letters of 'did he send you music list' are 'DEDUCT'.
(Other definitions for deduct that I've seen before include "Make a subtraction" , "Knock off" , "Subtract, take away" , "Remove" , "Withhold" .)
