Did you know that the most famous version of Psalm 40 is by the rock band U2?  For many years they ended most concerts singing, “I will sing, sing a new song.”  The “new song” (Hebrew: shir chadash) is most likely a technical Hebrew term for what psalms scholars usually describe as the “song of thanksgiving” -- a song that is sung after the psalmist has been delivered by the Lord from the jaws of some crisis.
