Key of G (Throwback)

I'm ready

Can I sing your song with your words?

Your cords and harmonies?

I can't go wrong when it's your melody

My auto-tune set to your heart

So speak through me

Your will be done

And I'll run this in your key

The key of G-O-D

The key of G-O-D

The key of G-O-D

The key of G-O-D

So work in me G-O-D

Yeah, G-O-D

Has anybody noticed this is G and D?
