Skladba Mercy je druhým singlom z albumu Drones. Premiéru mala v pondelok 18. mája vo vysielaní Rádia BBC 1.
Matt Bellamy sa k skladbe vyjadril takto: "V úvodnej linke 'Help me I’ve fallen on the inside', protagonisti vedia, že niečo stratili, že stratili samých seba. Práve tu, zisťujú, že zvíťazili nad temnými silami, ktoré boli predstavené v skladbe Psycho."
Help me, I’ve fallen on the inside
I tried to change the game
I tried to infiltrate
But now I'm losing
Men in cloaks
Always seem to run the show
Save me from the ghosts and shadows
Before they eat my soul
Yeah
Mercy
Mercy
Show me Mercy
From the powers that be
Show me mercy
Can someone rescue me
Absent gods
And silent tyranny
We're going under
Hypnotized by another puppeteer and
Tell me why the men in cloaks
always have to bring me down
Running from the ghosts and shadows
The world just disavows
Yeah
Mercy
Mercy
Show me mercy
From the powers that be
Show me mercy
Can someone rescue me
Show me mercy
Show me mercy please
Help me
I’ve fallen on the inside
And all the man in a cloaks
Trying to devour my soul
Show me mercy
From the powers that be
Show me mercy
From the gutless and mean
Show me mercy
From the killing machines
Show me mercy
Can someone rescue me
