Echarme otra is a colloquial phrase that literally translates to "throw myself another one," but in the context of the song, it means "to have another drink."
This phrase is interesting because it's a common, informal way to express the act of drinking more, especially when trying to forget something. The singer repeats this phrase, emphasizing his attempt to drown his sorrows and erase the memory of a past love, making it central to the song's theme of heartbreak and coping.
Ulices Chaidez and El Yaki team up for "Voy a Echarme Otra," a song about trying to forget someone who didn't appreciate them. The singer gave their "corazón y alma" [heart and soul] but it meant nothing to the other person. Now, to get over it, they're singing and drinking, hoping to erase the memory.
They keep saying, "Voy a echarme otra / Pa ver si se me borra / De una vez por todas / Tu mendigo recuerdo" [I'm going to have another one / To see if it erases / Once and for all / Your damn memory]. It's a relatable feeling when you're trying to move on but still feel that pull, admitting, "Aún siento que te quiero" [I still feel like I love you]. The drinks are a way to push that person out, because, as the lyrics say, "Tú en mi vida fuiste / Una persona pasajera" [You were a passing person in my life]. It's a blunt, honest take on heartbreak and trying to find a way to forget.
