It's just more of what the fans asked for in the end (6)
I believe the answer is:
encore
'end' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for encore that I've seen before include "Extra item at end of concert" , "Cry for repeat performance" , "Call to perform again" , "Play or sing it again" , "Repeated performance demanded by an audience" .)
