Paper that's still listened to (10)
I believe the answer is:
stationery
'paper' is the definition.
(I know that stationery is a type of writing paper)
'still listened to' is the wordplay.
'still' becomes 'stationary' (both can mean immobile).
'listened to' shows a homophone (sound like).
'stationary' is a homophone of 'STATIONERY'.
'that's' acts as a link.
(Other definitions for stationery that I've seen before include "Writer's needs" , "The papers, etc" , "Various items in paper" , "Files etc" , "Pens, pencils, paper etc" .)
