Reconócelo means "recognize it" or "admit it." It's a key word in this song, as the singer repeatedly urges the other person to acknowledge the truth of their feelings and the situation.
It's an engaging word because it implies a moment of truth and confrontation, making the listener wonder what exactly needs to be recognized. The repetition throughout the song makes it memorable and central to the narrative.
Have you ever been the person someone turns to when their main squeeze isn't giving them attention? That's exactly where Rombai and John C find themselves in "Reconócelo" [Recognize it]. It's a fun, confident track where they're basically telling this girl, "Baby, reconócelo, que fui yo / Al que le escribías cuando él no te contestó" [Baby, recognize it, it was me / The one you wrote to when he didn't answer you].
They're not holding back! Now that the other guy is back in the picture, they're urging her to tell him to find someone else because he "contigo perdió" [lost with you]. They're making it clear that they're the ones who truly care, saying "Yo te quiero para mí, para mí, por ti peleo la batalla" [I want you for me, for me, for you I fight the battle]. It's a bold declaration of love and a bit of a playful challenge to the girl to finally admit who she really wants. They're saying, "No podemos negar lo que estamos sintiendo" [We can't deny what we're feeling], so why fight it?
