"Mi Olvido" is a song by Espinoza Paz, a Mexican singer-songwriter. The lyrics talk about a toxic relationship where the speaker is constantly being shouted at and not allowed to defend themselves. The other person throws everything they can at the speaker, saying hurtful things, causing tears to fall. The speaker feels like they gave their best in the relationship, but in the end, it feels like they gain nothing. The chorus repeatedly mentions a sword of forgetfulness (espada de olvido) that the speaker will use to get back at their partner. They talk about how they will make the other person feel the same pain they are experiencing - sinking them into oblivion. The lyrics suggest that the speaker will leave at some point, leaving their partner to settle for nothing and making them feel the emptiness they caused. The "sword of forgetfulness" will pierce through their partner's soul. The song expresses a sense of revenge and the desire for the other person to experience the same kind of suffering they inflicted. It also implies that the speaker will move on and forget about their partner, leaving them with the emptiness they deserve.
