Put down; song (3)
I believe the answer is:
lay
I believe this is a double definition.
'put down' is the first definition.
(lay something down)
'song' is the second definition.
(poetic term for a song)
(Other definitions for lay that I've seen before include "Secular; set" , "Arrange" , "Not ordained; song" , "gamble" , "Deposit < , as a nest egg, was" .)
