Spurgeon on Psalm 42:4: "We might as well pray by machinery as praise by it"

OK, let me continue the flow of Spurgeon and the simplicity of congregational singing in NT worship.  Here is part of Spurgeon's exposition of Psalm 42:4 in The Treasury of David:

David appears to have had a peculiarly tender remembrance of the singing of the pilgrims, and assuredly it is the most delightful part of worship and that which comes nearest to the adoration of heaven. What a degradation to supplant the intelligent song of the whole congregation by the theatrical prettinesses of a quartette, the refined niceties of a choir, or the blowing off of wind from inanimate bellows and pipes! We might as well pray by machinery as praise by it.
