Pay for the loud music Dora's upset about (6)
I believe the answer is:
afford
'pay' is the definition.
(thesaurus)
'loud music dora's upset about' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'music' becomes 'f' ().
'upset' is an anagram indicator.
'about' means one lot of letters goes inside another.
'dora' is an anagram of 'aord'.
'f'+'f'='ff'
'ff' going inside 'aord' is 'AFFORD'.
'for the' is the link.
(Other definitions for afford that I've seen before include "Be able to buy" , "Yield!" , "Have the means to pay" , "Be able to spare the money" , "Able to bear the expense" .)
