Agonizando is a powerful and dramatic word meaning 'agonizing' or 'dying'. It's the present participle of the verb agonizar, which describes being in the final throes of death or extreme pain.
In this classic heartbreak anthem, the singer uses the word to describe his emotional state with the line "Agonizando, muy lento y muy fuerte" (Agonizing, very slowly and very strongly). It's a vivid, unforgettable word that perfectly captures the feeling of being completely overwhelmed by 'puro dolor' (pure pain).
This song from Puerto Rican group Son by Four is one of the most dramatic breakup anthems ever. It opens with the singer making a forbidden phone call to an ex. He knows he shouldn't be doing it, admitting, "Disculpa, sé que estoy violando nuestro juramento" (Sorry, I know I'm breaking our promise). He even knows she's with someone new! But he's so desperate he just needs to hear her voice, even for a second: "me hacía falta escuchar de nuevo / Aunque sea un instante tu respiración" (I needed to hear again / even for a moment, your breath).
He then launches into a full-blown plea, describing his pain in the most intense way possible. He's not just sad; he's "muriendo por verte" (dying to see you) and "Agonizando, muy lento y muy fuerte" (Agonizing, very slowly and very strongly). He feels empty, lost in a maze during the day, and at night, things get even worse. The nights, he says, taste of "puro dolor" (pure pain). He begs life itself to return his will to live, making this a truly over-the-top and unforgettable song about heartbreak.
