[Beautiful Days, Lovely Eyes] is a medium-tempo track filled with a warm and cozy atmosphere. It opens with an acoustic guitar and a whistling intro that evokes a sunny afternoon. As the song progresses, a rich layer of diverse instruments joins in, maintaining its initial warmth to the very end and leaving listeners with a delightful, lingering resonance."
