I believe the answer is:
ballads
'songs' is the definition.
(ballad is a kind of song)
'some tribal lad sang' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).

(Other definitions for ballads that I've seen before include "Soppy songs!" , "Popular songs" .)
