Orchestrate New Order back catalogue
I believe the answer is:
rearrange
'back catalogue' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how one could define the other.
'orchestrate new order' is the wordplay.
'orchestrate new' becomes 'rear' (I can't justify this - if you can you should believe this answer much more).
'order' becomes 'range' ('range' can be a synonym of 'order').
'rear'+'range'='REARRANGE'
Can you help me to learn more?
(Other definitions for rearrange that I've seen before include "Change the position(s) of" , "Move round" , "Put new structure" , "Change the position of" , "Make an anagram of" .)
