Dañado means "damaged" or "harmed." While the verb "dañar" (to damage) is common, its use here in the past participle as an adjective is particularly poignant and impactful.
In the song, the line "Sé que nos hemos dañado tanto" (I know we have hurt each other so much) powerfully conveys the deep emotional wounds inflicted within the relationship. It's a raw and honest admission of mutual harm, making it a memorable and emotionally resonant word in the context of the song's narrative of a broken relationship.
Big Soto's "TANTO.." is a really honest look at a relationship that's clearly on its last legs, but neither person seems ready to fully let go. He starts by asking, "No hablas, ¿qué haces aquí?" [You don't speak, what are you doing here?] and "¿Qué haces lejos de mí?" [What are you doing away from me?], which immediately sets up this push-pull dynamic. There's a moment where he says, "Gracias por regresar, igual no, prefiero no hablar" [Thanks for coming back, but no, I prefer not to talk], showing that even though he appreciates her return, he's also tired of the drama.
He admits, "De que hace rato estoy mal, no es como si algo va a cambiar" [That I've been bad for a while, it's not like anything will change], which is a pretty blunt acceptance of their situation. You can feel the confusion when he sings, "Y no sé por qué estás llorando, ¿Fue mi culpa? ¿Qué estás hablando?" [And I don't know why you're crying, Was it my fault? What are you talking about?], and then, "No sé por qué me gritas tanto, Sólo estábamos hablando" [I don't know why you're yelling so much, We were just talking]. It really highlights how communication has broken down between them. He knows they've both caused pain, saying, "Sé que nos hemos dañado tanto" [I know we've hurt each other so much], and even admits, "Yo miento igual que tú y no lo sabes" [I lie just like you and you don't know it]. It's a raw and relatable song about the messy end of a relationship where both people are hurting and struggling to move on.
