For me, it's the beautifully heart-breaking "Kuiama" by The Electric Light Orchestra

KUIAMA--Electric Light Orchestra

My, my Kuiama, she came in the morning
She smiled but the tears on her little face
Showed the pain that had been in that far off place
So sad, treated so bad.

My, my Kuiama, don't break your heart trying
To say how your ma and your pa passed away
And they left you to wander the ruin and decay
Real mean, that bullet machine.

See here Kuiama, now ten thousand miles
Is a long, long way and you're here today
And you won't go back so you might say
Hello, how do you do.

Kuia stop your crying, there's no bombs a'falling
No horsemen in the night a'riding
Through your dreams and tearing at
Your life, baby goodnight.

No more silver rain will hit your ground
And no more guns will sound
And no more life be drowned
No more trenches where the soldiers lie
And no more people die
Beneath that big black sky.

Wake up Kuiama, I got something to tell you
It's just I mean, well that is to say
That I'm trying to explain but I'll start again
For You, I must be true.

Kuia in this country, they got rules with no reason
They teach you to kill and the send you away
With your gun in your hand you pick up your pay
So cool, that no mercy tool.

Kuia please believe me, I just couldn't help myself
I wanted to run but they gave me a gun
And they told me the duty that I owed to my
Fatherland, I made my stand.

Kuia I just shot them, I just blew their heads open
And I heard them scream in their agony
Kuiama, she waits there for me
True blue, you saw it through
