Psalmnody: On why we sing the songs of God

A description and explanation of Psalm singing and why we do it. God wrote 150 songs and preserved them in the Bible. Psalmnody is a wonderful and meaningful part of authentically Christian worship. Psalm singing seems to be a requirement for Biblical worship. Psalm singing cannot be adequately replaced by contemporary worship songs nor by Exclusive Hymnody. God as he really is can easily be misrepresented by avoiding singing the Bible itself. Jehovah has jurisdiction over how he speaks and how he will be worshipped. Human compositions, prayers, sermons and songs are permissible but will always be merely human and so fallible, even if good and edifying. Psalmnody is part of our historic theological tradition. It is he exclusion of the Psalms from Christian worship that seems unreasonable. Why would we exclude the songs in the Bible from our worship of the God of the Bible?
