Wood sounds good to me (4)
I believe the answer is:
deal
I believe this clue is a double definition.
'wood' is the first definition.
(deal is a kind of wood)
'sounds good to me' is the second definition.
(both can be said to express agreement)
(Other definitions for deal that I've seen before include "Board" , "split deck" , "Bargain, contract" , "Business arrangement in timber" , "Distribute playing cards" .)
