Canção da América was written by Milton Nascimento and Fernando Brant and released in 1980, becoming one of Brazil's most enduring songs about friendship. Its line about keeping a friend on the left side of the chest entered everyday language, quoted in cards, speeches and social posts. The excerpt circulates online as a short audio for dedications, especially around farewells, graduations and reunions, because Brazilians instantly recognise the melody and associate it with loyalty, distance and affection that survives time apart.
