Covers for songs (4)
I believe the answer is:
lays
This clue is a double definition.
'covers' is the first definition.
(as in laying something down on something else)
'songs' is the second definition.
('lay' is a literary term for a song)
'for' is the link.
(Other definitions for lays that I've seen before include "Sets down the old songs" , "Puts down; songs" , "Arranges" , "Puts down the old ballads" , "Places (bets?)" .)
