'Songs' in the Bible

As they were coming [home], when David returned from killing the Philistine, the women came out of all the cities of Israel, singing and dancing, to meet King Saul with tambourines, [songs of] joy, and musical instruments.

And the servants of Achish said to him, Is not this David, the king of the land? did they not make songs about him in their dances, saying, Saul has put to death thousands, and David tens of thousands?

Is this not David, who was named in their songs, when in the dance they said to one another, Saul has put to death thousands, and David tens of thousands?
