Lyrics: All That Remains. The Air That I Breathe.

I will not relent no no
Never live with defeat never falter
This like the air that I breath
I will not choke on failure

I am a mortal man
But I'm no falling I'm not broken yet
I'm am a mortal man
But I'll hold tight to my beliefs now

I have suffered defeat, pain, loss
Still I push to the edge, never falter
For this cements my beliefs
I'll remain my own master

I will not relent no no
Never suffer defeat, never falter
For this cements my beliefs
I will not choke on failure

I will not relent
