In too many anti-EP works I find the argument that not all of the Psalms in the Psalter were used in the Temple. A helpful rebuttal is found in "Which Psalms Were Sung in the Temple?" by J. A. Smith from Music & Letters, Vol. 71, No. 2 (May, 1990), pp. 167-186. It should be noted that he is not dealing with anti-EP works but is taking a scholarly look at the Psalms.
