Unfriendly feeling one puts on record still (6)
I believe the answer is:
needle
I believe this is a double definition.
'unfriendly feeling' is the first definition.
(needle can mean antagonism)
'one puts on record still' is the second definition.
(as in a needle on a record player)
(Other definitions for needle that I've seen before include "Thin pointer; antagonise" , "Annoy by constant criticism" , "Pin" , "Dial pointer; annoy" , "Item for sewer" .)
