Steve -- E J Young and Westminster OT faculties generally do not do justice to the superscriptions of the Psalms. Remove the credibility of the superscripts and you can place the book in any era one pleases. I don't favour a post-exilic editor for the reasons mentioned in the quotation. I find it interesting that the NT presupposes Davidic authorship even where the titles of the Psalms are anonymous. Blessings!
