"Lonely was the song I sang, 'til the day you came
Showing me a better way and all that my love can bring
Oh half of my heart's got a grip on the situation
Half of my heart takes time
Half of my heart's got a right mind to tell you
That I can't keep loving you
Oh, with half of my heart
With half of my heart
But I can't stop loving you
But I can't stop loving you"

Oh John Mayer.
