Don McLean's song 'Infinity' reflects on the boundless nature of love, hope, and existence. The song delves into the themes of eternal love and the cyclical nature of life, suggesting that some aspects of our experiences are timeless and transcend the finite boundaries of physical life. Throughout the lyrics, McLean often employs poetic imagery and metaphors, which evoke a sense of wonder about the universe and our place within it. Poignant moments in the song include references to stars, endless journeys, and the continuum of time, all of which underscore the notion of infinity and the enduring nature of the human spirit.
