(Same chords as over)
I know there's something more
I don't wanna die
I don't wanna waste another day or night
I know there's something more
Than what we're living for
I see it in the stars
I feel it on the shore

I know there's something more
I don't wanna die
I don't wanna waste another day or night
I know there's something more
Than what we're living for
I see it in the stars
I feel it on the shore

I know there's something more,
I know there's something...
