The phrase a flor de piel literally translates to "at the flower of the skin". It's a beautiful Spanish idiom used to describe feelings that are raw, intense, and right on the surface, much like a nerve ending.
In this nostalgic RBD classic, the lyrics "Y a flor de piel hay un adiós difícil de olvidarlo" (And on the surface, there's a goodbye that's hard to forget) perfectly capture the sensitive emotion of a past love that still feels very present.
Have you ever run into an ex and felt that old spark again? That's exactly what RBD is singing about in "Aun Hay Algo." The song is all about two people with a shared past who are wondering if their old feelings are coming back. They admit they have a history, one that ended with a painful goodbye that's "difícil de olvidarlo" (hard to forget).
But even with that difficult past, there's a powerful sense of hope. The singer wonders if seeing them makes their ex happy, asking, "Quizás entre los dos / Aún hay algo de amor" (Perhaps between the two of us / there's still some love). It's a song full of questions and longing, building up to a desperate plea in the bridge: "Mírame bien / Que aún yo sigo aquí... No sé vivir sin ti" (Look at me closely / I'm still here... I don't know how to live without you). It's the ultimate anthem for anyone hoping for a second chance at a great love.
