Somepony That You Used to Know

But there's no way you can cut me off
My perfect day is gonna happen and no one can stop me
And now I will feed on your love
'Cuz it turns out I'm a Changeling and your feels are lunch
No, I didn't have to stoop so low
Throw your betrothed in a cavern and then blast your sister
I guess a girl can have it all
Now I'm just somepony that you used to know
