Rubor literally translates to "blush" or "redness", often referring to the natural reddening of the face due to shyness, embarrassment, or emotion. It's a less common word in everyday conversation compared to more direct terms for color.
In this song, the lyric "Y que a las flores pudiera pedir sin rubor sus fracasos" (And that I could ask the flowers for their failures without blush) uses rubor to imply a lack of shame or embarrassment. The singer imagines a world where even flowers could openly share their imperfections without any hesitation or 'blush', adding a poetic and vulnerable layer to the lyrics.
“Lo Primero Que Haría” is a passionate declaration of love taken to the furthest extremes. The Spanish crooner imagines impossible scenarios—escaping the grave, descending from heaven, stealing stars from the sky—just to prove that his very first impulse would always be to hold and kiss the person he loves. Each fantastical image piles on another layer of devotion, showing that no force, not even death or divine judgment, can weaken the pull he feels.
Yet this love has a darker edge. The lyrics confess that, if he saw his beloved in someone else’s arms, jealousy would weigh on him like boulders. He would beg God to heal the pieces of his shattered heart, because the same absolute love that drives him to give up his life could also push him to take another’s. In short, the song paints love as an overwhelming force—tender and poetic, but also volatile and consuming—making it clear that for this singer, love sits above all things.
