No 12 in AOV NG is Bless the Lord (Ps 103:1-6) and is by Marcy Weckler Barr, a very experienced music liturgist from Chicago. The refrain would be fine for when this psalm comes up, as it is straight from ICEL text. The verses are noted to be written by the songwriter and if used makes this just a good song, not something to be used as a psalm in liturgy. If sung I suspect they are cantor material in any case.
If you haven’t got AOV NG you can buy at single sheet at WLP.
There is no sample at the AOV site and so I had no idea how it went apart from the tempo so the backing is basic and is just for learning the tune if you have the words and music.
Refrain:
Bless the Lord, O my soul, bless the Lord my soul!
Bless the Lord, O my soul, bless the Lord my soul!
