Cambia, todo cambia comes from Todo Cambia, written in 1982 by Chilean songwriter Julio Numhauser while in exile, and later made famous across Latin America and Spain by Argentine singer Mercedes Sosa. The song lists how seasons, people and even thoughts change, becoming an anthem for adaptation and resilience rather than a protest slogan. Online, short clips of the refrain circulate on social media for montages about ageing, moving cities, lost friendships and transformed places, where its familiar melody signals change without needing the full lyrics explained.
