Ganado literally translates to 'livestock' or 'cattle', but in modern Spanish dating slang, it is used humorously to describe a 'roster' of people you are casually seeing.
In the lyrics, the singer laments his breakup by saying, "Y tú ya traes nuevo ganado" (And you already bring a new roster). He uses this clever double meaning to point out how quickly his ex moved on to a whole new group of suitors.
In "Abcdario", Mexican artist Edén Muñoz teams up with Junior H to deliver a blunt, darkly funny track about post-breakup spiral and bruised ego. The narrator was head over heels, but it turns out he was only ever a "casi algo" (almost-something) or a "por mientras" (a placeholder). Now he is reeling because his ex has moved on so fast she already has "nuevo ganado" (new cattle, Mexican slang for a roster of new love interests), while he has not even managed to delete her photos. To cope, he runs through the entire alphabet of new dates: "Me acabé el abecedario, desde la A hasta la Z, y hasta repetí algunas letras" (I finished the whole alphabet, from A to Z, and I even repeated a few letters).
The track is packed with great Mexican street slang and relatable misery. The narrator admits that going out on dates brings no joy, so he drinks heavily ("le doy fondo al vaso" / I chug my glass to the bottom) and searches Tinder for women who look like his ex's clone. He tosses out sighs of frustration like "Chale" (Damn / Bummer) and jokes that he needs glasses to see that she never cared, or maybe just a psychologist because she has him heading to therapy ("Me tienes yendo a terapia"). It is petty, self-aware, and bitterly honest about how messy life gets when you try to numb real heartbreak with casual flings.
