This is what I currently listen to when I can't sleep:
"Goodnight, my Angel"
the first track on the album by cantabile called "Lullabyes and Goodbyes"
The words seem to be sung to me by my lover, or my Lover, and are immensely comforting. I love all the arrangements of all the songs on the album - how often can you say that of a whole album! It was an inspired and generous gift from a piano pupil's mother.
This is what I sing as a "worship" song in the car (or about my husband too, come to think of it!)
"To know him is to love him"
from Steeleye Span's album "Now We Are Six"
Not from the usual repertoire of worship songs!
