Discutírtelo is a fascinating word because it's a single word that combines the infinitive verb "discutir" (to discuss), the indirect object pronoun "te" (you), and the direct object pronoun "lo" (it).
In the song, the singer says, "Yo no intento discutírtelo" (I'm not trying to discuss it with you). This compact word perfectly captures the speaker's resignation and unwillingness to argue about the departure of their loved one, making it a unique and memorable choice.
This song is a passionate plea from someone who knows a relationship is ending but isn't ready to let go. He's trying to convince his partner to stay just one more night, even promising, "Prometo no tocarte, está segura" [I promise not to touch you, be safe]. You can feel his desperation as he admits, "Hay veces que me voy sintiendo solo" [There are times I feel lonely] and acknowledges her "sonrisa tan definitiva" [such a definitive smile] that opened his "paraíso" [paradise].
He's clearly hurt by her request to be friends, exclaiming, "¿Y amigos para qué, maldita sea? A un amigo lo perdono, pero a ti te amo" [And friends for what, damn it? I forgive a friend, but I love you]. He even reveals his vulnerability, saying his problems are called 'you': "Que mis problemas, ¿sabes qué? Se llaman 'tú'" [That my problems, you know what? They're called 'you']. It's a raw and honest look at the pain of a breakup, where one person is still deeply in love while the other is ready to move on, leaving him with "esta historia entre tus dedos" [this story between your fingers].
