Hears a CD prepared for party game (8)
I believe the answer is:
charades
'party game' is the definition.
(I've seen this before)
'hears a cd prepared' is the wordplay.
'prepared' is an anagram indicator.
'hears'+'a'+'cd'='hearsacd'
'hearsacd' is an anagram of 'CHARADES'.
'for' is the link.
(Other definitions for charades that I've seen before include "Miming parlour game" , "Party guessing game" , "Game in which answers are acted out" , "Guessing game where words are acted out" , "Miming games" .)
