"Te Hubieras Ido Antes" means "You should have left sooner", and that title is the whole complaint. The singer is not upset that she left. He is upset about the timing: "¿Por qué no te marchaste cuando aún no eras tan indispensable?" (Why didn't you leave when you still weren't so essential?). She made him fall for her, "hiciste todo para enamorarme" (you did everything to make me fall in love), and now she wants him to forget her smile and her caresses.
The first half is heartbreak with a lot of logic in it: "Me suena tan ilógico" (it sounds so illogical to me) that she now says it wasn't her fault. Then the spoken break flips the mood completely. "Te vas mucho a la chingada" is a very rude Mexican way of saying "go to hell", followed by an even harsher insult and "a la verga", roughly "screw it". So this one is not classroom material. It ends with "Pásame la botella, compa" (pass me the bottle, buddy), which tells you exactly how he plans to get over her. Compa, short for compadre, is the everyday Mexican word for buddy.
