Psalms 144:9 talks about singing a new song, but Ecclesiastes 1:9 suggests there is nothing new under the sun, implying futility in seeking new expressions.

Contrasts with Psalms 144:9's expression of joyous singing, as Lamentations 5:14 highlights sorrow, stating that elders have ceased from the gates, and young men from their music.
Lamentations 5:14: The elders have ceased from the gate, the young men from their musick.
Contradiction with Amos 5:23
