It spawned the top five singles "+ (Más)" featuring Cali y El Dandee and "Corazón Sin Vida" featuring Sebastián Yatra. Aitana ventured into acting in the Disney+ original series La Última (2022), for which she also recorded the soundtrack. She later explored electropop with her 2023 release Alpha, featuring the singles "Los Ángeles" and "Las Babys".
