Emotional Songs about Loss/Death Needed for Documentary Film

The title says it all. We are looking for emotional songs about loss for an upcoming feature-length documentary film about the war in Ukraine. Male or female vocals are fine, but we need your lyrics! Songs must be original (ONE STOP). All genres are ok, as the mood, feel, and lyrical content are what's most important. Tracks should be down-tempo. Lyrics/vocals will be featured, so a high quality vocal performance and mix is a must.
