Locura translates to "madness" or "craziness", but it often carries a romantic or passionate connotation in Spanish, implying a wild or impulsive act.
In "Frente A Frente," the lyrics mention "Y alguna vez haciendo una locura / Un beso y a la fuerza" (And sometimes doing something crazy / A kiss and by force). This suggests a desperate, perhaps final, act of passion or defiance in a relationship that is fading, making it a compelling and emotionally charged word.
Have you ever sat directly opposite someone and realized you have completely run out of things to say? That exact, awkward freeze is what Jeanette sings about here. In "Frente A Frente" (Face to Face), a relationship has run entirely out of fuel. She starts by tallying up the leftovers: "De nuestro amor apenas queda nada / Apenas mil palabras" ("Hardly anything is left of our love / Barely a thousand words"). That phrase apenas mil palabras sounds like a lot until you realize a thousand words lasts about ten minutes of talking. After that, it is just cold air.
She sings with her signature whispery Spanish delivery, which makes lines like "Un beso y a la fuerza" ("A kiss, and forced at that") sound almost chillingly casual. To survive the breakup, they throw each other scraps of basic politeness: "Queda un gesto amable / Para no hacer la vida insoportable" ("A polite gesture remains / So as not to make life unbearable"). The whole scene comes down to the title moment. Two people sit frente a frente (face to face), look straight down at the floor, and realize they only want to cry because the conversation is officially over.
