One

One' by Metallica delves into the nightmarish reality of a soldier severely wounded in battle, deprived of all senses and limbs, trapped within his own body, pleading for death as his only escape from unending suffering.

Metallica's 'One' portrays intense anguish and a visceral cry for relief through the perspective of a war veteran, who becomes a prisoner within his own body after a landmine explosion. The song explores themes of isolation, helplessness, and the existential dread of living a life devoid of sensory and motor capabilities, conveying a powerful anti-war message. The use of haunting lyrics and shifting musical intensities mimics the protagonist's psychological and emotional turmoil, ultimately questioning the very essence of what it means to be alive when all quality of life is lost.
