End of the world

Why does the sun go on shining why does the sea rush to shore
Don't they know it's the end of the world cause you don't love me anymore
Why do the birds go on singing why do the stars glow above
Don't they know it's the end of the world it ended when I lost your love
I wake up in the morning and I wonder why everything's the same as it was
I can't understand no I can't understand why life goes on the way it does
Why does my heart go on beating why do these eyes of mine cry
Don't they know it's the end of the world it ended when you said goodbye
