Saddest songs

"Eric Clapton - Tears In Heaven"
Youtube : YouTube .
Clapton's son died in a car accident and this song is dedicated to him... I became very sad when I listen to it. I even write my document with the help of writing apps and its origin. This is how the song begins:
"Would you know my name
if I saw you in heaven?
Would it be the same
if I saw you in heaven?
I must be strong and carry on
'Cause I know I don't belong here in heaven"

For me,

Six More Miles by The Residents
 
The Yardbirds - Still I'm Sad

See the stars come falling down from the sky,
Gently passing, they kiss your tears when you cry.
See the wind come softly blow your hair from your face,
See the rain hide away in disgrace.
Still I'm sad.
For myself my tears just fall into dust,
Day will dry them, night will find they are lost.
Now I find the wind is blowing time into my heart,
Let the rain fall, for we are apart.
Still I'm sad,
Still I'm sad,
Oh, Still I'm sad.
