The third installment in bachata king Romeo Santos genre-crossing Formula series continues to highlight his persuasive, gentle voice and versatile chops. "Siri" features reggaeton newcomer Chris Lebron, alternating Latin urban and Afrobeat styles. Christian Nodal joins Santos on "Me Extrano," an utterly romantic mariachi ballad. The set also includes four merengue legends -- Tono Rosario, Fernando Villalona, Rubby Perez, and Ramon Orlando -- forming a collaborative chorus on the cooker "15,500 Noches." Rosalia joins Santos on "El Panuelo," while Justin Timberlake jumps in on the steamy "Sin Fin."
