Short song heard from Spooner's room (6)
I believe the answer is:
leeway
'room' is the definition.
(both can mean freedom or space to move or act)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for leeway that I've seen before include "Space for free movement" , "Give" , "Drift - scope for action" , "Scope for freedom of movement or action" , "play" .)
