King receives note pertaining to reshuffle (5)
I believe the answer is:
remix
'king receives note pertaining to reshuffle' is the definition.
I can't judge whether this defines the answer.
'king receives note' is the wordplay.
'king' becomes 'rex' ('king' in Latin).
'receives' indicates putting letters inside (inserted letters are received).
'note' becomes 'mi' (as in 'do re mi').
'rex' going around 'mi' is 'REMIX'.
Can you help me to learn more?
(Other definitions for remix that I've seen before include "Revised pop song" , "New arrangement of tracks" , "Updated record" , "New blend (recording, recipe, etc)" , "Make a new version of a recording" .)
