In spite of their poignancy and availability, the lament psalms are not much used. If you look in the back of the hymnals of most major Protestant denominations, you will find perhaps Psalm 1, then skip to 8 and 19 and perhaps 22. Even when lament psalms are included, they are not sung much. In Roman Catholic and liberal Protestant usage, most of the lament psalms simply do not exist. (Anglicans use the lament psalms, but set them to such wonderful music that you don't notice what is being said!)
