Barato means "cheap" or "inexpensive." While it's a common word, its use in the phrase "juego barato" (cheap game) in this song is particularly interesting and evocative.
In the context of the lyrics, "juego barato" refers to a manipulative or low-value relationship game. It implies that the emotional games being played are not only unfair but also lack genuine worth, making the word "barato" carry a deeper, more metaphorical meaning beyond just cost.
Antonio Ríos brings us a song about a relationship that's just not working, and he's finally had enough. He feels like his partner is playing a "juego barato" [cheap game] with his emotions, ignoring him when he tries to talk. He's tired of being told she's the "mujer perfecta" [perfect woman] if she doesn't make him happy.
He remembers how she "nunca escuchabas" [never listened] and would go off with someone else, leaving him alone. He gave her "todo" [everything], but she "nunca sientes nada" [never feels anything]. Now, he's ready to move on, declaring, "me voy a encantar de ser feliz" [I'm going to love being happy]. He's opening the door and letting her go, even if his heart has to accept the "error" [mistake] as part of the journey to forgiveness.
