Empecina comes from the verb empecinarse, meaning to insist or persist stubbornly, often against reason or difficulty. It's a less common, yet very evocative word.
In the song, it's used in the line "Por la fe que lo empecina" (For the faith that makes him stubbornly persist). This highlights the protagonist's unwavering, almost defiant, belief despite the harsh realities of life and love, making it a powerful and memorable choice.
Have you ever felt so hurt by love that you just can't bring yourself to try again? Luis Miguel's "Uno" is all about that feeling. He sings about someone who's been through so much, fighting and struggling for love, only to end up with a broken heart. He says, "Uno va arrastrándose entre espinas" [One goes dragging oneself among thorns], which really paints a picture of how painful it's been.
It's like he's lost his ability to love freely, saying, "Si yo tuviera el corazón, el corazón que di" [If I had the heart, the heart I gave away]. He's so wary now, wondering if he could even trust new love, because he's afraid of repeating past mistakes. He's been so betrayed that he's "Vacío ya de amar y de llorar tanta traición" [Empty now of loving and crying so much betrayal]. It's a really powerful song about the aftermath of heartbreak and the struggle to open up again.
