Heartaches by the Number es una canción transmitida en Radio Black Mountain en Fallout: New Vegas, escrita por Harlan Howard en 1959 e interpretada por Guy Mitchell en la versión que aparece en el juego.
Heartache number 1 was when you...left me,
I never knew that I could hurt this way,
And heartache number 2,
Was when you...come back again,
You came back and never meant to stay.
Now I've got heartaches by the number,
Troubles by the score,
Every day you love me less,
Each day I love you more,
Yes, I've got heartaches by the number,
A love that I can't win,
But the day that I stop counting,
That's the day my world will end.
Heartache number 3 was when you...called me,
And said that you was coming back to stay,
With hopeful heart I waited,
For your...knock on the door,
I waited but you must have lost your way.
