Franqueza translates to "frankness" or "honesty." It's a less common word than honestidad and carries a slightly stronger connotation of directness and sincerity.
In the song, the lyrics state, "La humildad y la franqueza son armas muy poderosas" (Humility and frankness are very powerful weapons). This highlights the value the singer places on straightforwardness and truthfulness as essential qualities for a "hombre de ley" (man of the law/integrity), making it a key theme of the song.
Fidel Rueda's "Hombre De Ley" is a powerful anthem about hard work, humility, and staying true to yourself. He sings about the sacrifices he made to get where he is today, saying, "a mà me costó mucho trabajo para llegar hasta aquÃ, sacrifique la familia y algunas amistades por un sueño que cumplir" [it cost me a lot of work to get here, I sacrificed family and some friendships for a dream to fulfill]. He's not afraid to tell off those who might be jealous of his success, advising them to "mejor sigan el ejemplo y no se preocupen por mÃ" [better follow the example and don't worry about me].
Fidel emphasizes that he's a man of peace and hard work, not violence, but he also warns those who might try to cross him, saying, "al que se brinque las trancas aquà traigo un juguetito siempre admiró para accionar" [whoever jumps the fence, I have a little toy here always ready to activate]. He credits his success to God's blessing and the powerful combination of "la humildad y la franqueza" [humility and frankness], which he calls "armas muy poderosas que no cualquiera las porta, nomás los hombres de ley" [very powerful weapons that not just anyone carries, only men of law]. It's a great song about earning your way and standing firm in your principles.
