Copies of timeless recordings (4)
I believe the answer is:
apes
'copies' is the definition.
('ape' can be a synonym of 'copy')
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for apes that I've seen before include "Parrots" , "Peas (anag)" , "Zoo animals" , "Mimics like primates" , "Species of primate" .)
