Brisa means "breeze" in Portuguese. While it might seem like a simple word, its use in this song is quite poetic and evocative.
In "Lado B," IZA sings about "a brisa corrida da vida" (the hurried breeze of life) that brings people together. This metaphor personifies life's fleeting moments as a gentle yet swift force, making the word "brisa" stand out as a beautiful and meaningful element in the lyrics.
IZA sings about falling into a love that felt inevitable: “Sim foi, a brisa corrida da vida nos juntou” (“Yes it was, life's hurried breeze brought us together”). Rather than settling for the easy, familiar side of romance, she wants to show her partner the “lado B” — the B-side — “Vou te mostrar o lado B do amor” (“I'll show you love's B-side”), the rawer part few people ever get shown.
The chorus turns into a kind of surrender, repeating “Deixa o amor te levar” (“Let love take you”) and then “Deixa o amor elevar” (“Let love elevate”). By the bridge she makes the whole idea practical: “A vida é curta demais então pense, que o lado bom do amor é a gente que faz” (“Life's too short so think, that love's good side is what we make”). Love here isn't found waiting — it's something the two of them build.
