Demasiado means "too much" or "excessively." While it's a common word, its repetition and emphasis in the song's title and chorus, "Más que demasiado" (More than too much), elevate its significance.
In this context, it's used to express an overwhelming, almost unbearable intensity of emotion—specifically, missing someone so much that it's "more than too much." This hyperbolic usage makes it memorable and central to the song's theme of intense longing.
Have you ever felt like saying goodbye to someone you love is just the worst? That's exactly what Alexander Acha is singing about in "Más que demasiado" [More Than Too Much]. He's stuck in this loop where goodbyes keep happening, and even though he knows it's coming, it still "me mata" [kills me].
He really hates that door frame because it's where the goodbyes happen, breaking their "encanto" [charm]. He even says, "No te has ido todavía y aún así te extraño" [You haven't left yet and I already miss you]! It's that feeling of loving someone so much that even a minute apart feels like too long. He just wants "otro minuto" [another minute] and for them to "no dejes de besarme" [not stop kissing me]. It's a super relatable song about how hard it is to say goodbye when you're head-over-heels in love.
