When I was a kid, 'Puff the Magic Dragon' would mess me up something awful in a way I couldn't then understand. Probably still could - I daren't give it a try.
I think 'Elizabeth, You Were Born To Play That Part' by Ryan Adams is probably it. By all/his accounts, it's from the perspective of a woman to her stillborn baby. The music and his voice (and the words) when he sings 'Wherever you are, I hope you're happy now/I'm caught in a dream and can't get out' generally gets me welling up. The song is in two parts - indeed, halves. Piano and voice, and then fading into a fuller instrumental.

For you I'd do anything
Tear myself in two
Just to hear you breathe
Calculate the changes that in time
Turn to nothing and then multiply
Yourself by my pain
Over you is where I stand
I wish I knew why
But I don't understand
I'm waiting on someone that just won't show
And every night it seems like there's no tomorrow
Not that you will ever know
Wherever you are, I hope you're happy now
I'm caught in a dream and I can't get out
I'm caught in a dream
I'm caught in an endless dream
Wherever you are, I hope you're happy now
I'm caught in a dream and I can't get out
I'm caught in an endless dream
And I'm not strong enough to let you go
And I have tried everything
But that
Elizabeth
