Sets down songs (4)
I believe the answer is:
lays
I believe this clue is a double definition.
'sets down' is the first definition.
(I've seen this in another clue)
'songs' is the second definition.
('lay' is a literary term for a song)
(Other definitions for lays that I've seen before include "How Pertelote produces" , "literary works?" , "Places (bets?)" , "Produces eggs" , "Arranges" .)
