Today's selection is "Circumdederunt me," by Cristóbal de Morales; a piece that is far more peaceful (melodically) than its words might suggest. (And here's the whole playlist.)
Circumdederunt me gemitus mortis
dolores inferni circumdederunt me.
The groanings of death have encircled me
the sorrows of hell have enclosed me.
