Brahms: "O Tod, wie bitter bist Du?" from Vier ernste Gesänge, Op. 121/3

1. how you come across to it:
It keeps running in my head. "O Tod, O Tod."

2. why this piece?
This is what you see when you switch on the television recently.

3. (and...)
Youtube.com has a version sung by Dietrich Fischer-Dieskau running with the score.
