Beaten up prior to producing medley (9)
I believe the answer is:
potpourri
'medley' is the definition.
(synonyms)
'beaten up prior to' is the wordplay.
'beaten' is an anagram indicator.
'up'+'prior'+'to'='uppriorto'
'uppriorto' is an anagram of 'POTPOURRI'.
'producing' is the link.
(Other definitions for potpourri that I've seen before include "Petals and spices to perfume a room" , "Scented petals and spices" , "Perfuming mixture" , "Mixture of dried, scented items" , "A medley of popular tunes" .)
