“Cobaia” turns the idea of a job application into a cheeky love proposal. In this upbeat sertanejo hit, the singer volunteers for every “position” that will keep her close to the one she desires: from brushing hair and guarding dreams to being the first lips tested after a fresh shave. She happily signs up as a cobaia (a guinea pig) so her crush can experiment with kisses, plans, and promises on her first, hoping the trial run becomes a permanent arrangement.
Behind the playful lyrics lies a message of bold devotion and light-hearted humor. Lauana Prado, joined by Maiara & Maraisa, celebrates the joy of offering unconditional affection, wrapped in catchy melodies and relatable everyday scenes. It is a fun reminder that sometimes love starts with volunteering for the simplest tasks—then grows into an irresistible bond filled with warmth, laughter, and plenty of “test” kisses.
