Mandamiento translates to "commandment," a word often associated with religious or moral laws. It's an intriguing choice in a romantic song, making it stand out from typical love song vocabulary.
In the lyrics, Alejandro Fernández sings, "Tengo ganas de inventarle un mandamiento a mis pecados" (I want to invent a commandment for my sins). This line suggests a desire to redefine or even justify his actions and desires within the context of his intense feelings, adding a layer of depth and playful rebellion to his longing.
Every other line in "Tengo Ganas" starts with the same four words: "tengo ganas de," meaning "I feel like" or "I want to." Alejandro Fernández turns that phrase into something close to a chant. He opens with "Tengo ganas de acostarme" ["I feel like going to bed"], then "Con la fe de tu mirada" ["With the faith of your gaze"]. The wanting doesn't let up from there. He wants to wait for her in the park. He wants to give in to "tu mas dulce petición" ["your sweetest request"].
Then one line breaks the pattern: "Pero no te tengo a ti" ["But I don't have you"]. It's the only sentence in the song that isn't a wish, and it explains all the others. He answers it by wanting even harder, singing "Tengo ganas de soñar despierto" ["I feel like daydreaming"] and "Remplazar mis soledad por tu silencio" ["Replace my loneliness with your silence"]. The chorus he keeps returning to, "Tengo ganas de que tengas ganas de tenerme a mí" ["I feel like you feel like having me"], asks for something bigger than her presence. He wants the wanting itself to go both ways.
