Verse 1:
Yo Yo Yo
What mercy what mercy
I'm feeling so empty
I'm feeling so lost
I'm feeling like I'm losing my grip
Chorus:
What mercy what mercy
You took my heart and left me with nothing
What mercy what mercy
You took my love and left me with nothing
Verse 2:
I thought we were forever
I thought we were one
But now I see you for what you are
A heartless soul with no remorse
Chorus:
What mercy what mercy
You took my heart and left me with nothing
What mercy what mercy
You took my love and left me with nothing
Bridge:
I'm crying in the dark
Trying to find a way to make sense of it all
But you won't leave me alone
You won't let me rest in peace
Chorus:
What mercy what mercy
You took my heart and left me with nothing
What mercy what mercy
You took my love and left me with nothing
Outro:
What mercy what mercy what you did to me.
