I was recently reminded of how much I like the (only) two songs I have by an artist named Nathan Clark George. They were offered here as free downloads several months ago. They are his attempt at putting Psalms 111 and 24 to music.
Many of the Psalms were intended to be sung (just think of how many musical notations there are in the superscriptions - e.g. "to the choirmaster" and "with stringed instruments" and "for the flutes"). Nathan Clark George can help you sing (and thus remember, and pray) the Psalms.
