Remixed CD needs to come down (7)
I believe the answer is:
descend
'come down' is the definition.
(synonyms)
'remixed cd needs' is the wordplay.
'remixed' indicates an anagram.
'cd'+'needs'='cdneeds'
'cdneeds' with letters rearranged gives 'DESCEND'.
'to' is the link.
(Other definitions for descend that I've seen before include "Move downwards" , "Plunge" , "Go down" , "Come down" , "Move downward" .)
