Compostura translates to "composure" or "self-control." It's an interesting word because it's not as common as other synonyms, and it often appears in contexts where someone is losing or maintaining their emotional balance.
In this song, the lyrics describe a moment of conflict: "Cuando llego tarde a casa y pierdo la compostura" (When I come home late and lose my composure). This vividly portrays the character's loss of self-control during an argument, making it a memorable and emotionally charged word.
Have you ever been in a relationship where you and your partner are totally different, but you just can't imagine being without them? That's exactly what La Adictiva sings about in "Nada Iguales" [Nothing Alike].
The singer is trying to convince his love not to leave, reminding her of their "momentos mas bonitos" [most beautiful moments]. He admits to his flaws, like coming home late and losing his temper, saying things like "no me digas nada" [don't tell me anything] when she asks "¿qué te pasa?" [what's wrong with you?]. He even confesses to getting distracted by other women when they're out with friends! Despite all their fights and how different they are – he's the "culpable" [guilty one] and she's the "inocente" [innocent one], he's the "villano" [villain] and she's the "esclava" [slave] – he still loves and cares for her. He hopes she'll always be with him because she's "lo mejor que me ha sucedido" [the best thing that has happened to me].
