Sobrevivientes literally means "survivors". This word is incredibly powerful in the context of this song, which compares a fast-moving, intense love affair to an accidente (accident).
Jesse & Joy sing, "Y a nuestra velocidad, no hubo sobrevivientes" (And at our speed, there were no survivors). This dramatic line metaphorically describes the complete and total end of the relationship. It paints a vivid picture of a love so intense and fast that it inevitably crashed, leaving neither person's heart, nor the relationship itself, intact.
This song from Mexican duo Jesse & Joy uses one big, dramatic metaphor for a failed relationship: a car crash. The singers look back on a love that moved way too fast, saying, "Fuimos tan deprisa / Que se nos apagó la risa" (We went so fast / that our laughter died out). The whole thing ended just as quickly, with a simple phone call in the early morning. They realized too late that "el amor es como un accidente / No lo ves hasta verlo de frente" (love is like an accident / you don't see it until it's right in front of you).
What's left after the crash? A lot of pain and some surprisingly kind feelings. The singer finds it hard to wake up alone and misses the way their ex used to kiss. But they also sent a New Year's wish for their ex to find "Un amor sincero, aunque no sea yo" (A sincere love, even if it's not me). In the end, the conclusion is brutal and sad: because of their speed, "No hubo sobrevivientes" (There were no survivors).
