Lyrics:

It's my heart you're stealing
It's my heart you take
It's my heart you're dealing with
And it's my heart you'll break

It's my heart you're taking
It's breaking bit by bit
It's my heart you're dealing with
But you don't know about it

If you'd feel like I feel
And if you'd know what I know
I don't think you'd ever play me
I know you'd never play me
