"Circumdederunt me," by William Byrd. (And the playlist, of course.)
Circumdederunt me dolores mortis,
et pericula inferni invenerunt me.
Tribulationem et dolorem inveni,
Et nomen Domini invocavi.
O Domine, libera animam meam.
The sorrows of death have compassed me:
and the perils of hell have found me.
I met with trouble and sorrow:
And I called upon the name of the Lord.
O Lord, deliver my soul.
