Saturar is a powerful verb that literally means "to saturate" or "to fill completely". It's a beautiful cognate that is easy for English speakers to recognize, but it's not commonly used in everyday conversation.
In this emotional ballad, Carlos Rivera sings "La quiero saturar por contemplar / Tus ojos..." (I want to saturate it by contemplating / Your eyes...). He is referring to his memory, expressing a deep desire to fill it to the brim with the image of his loved one, creating a vivid and poetic picture of cherishing a perfect moment.
Mexican singer Carlos Rivera takes a classic dramatic idiom and builds a whole romantic philosophy around it in "Me Muero". In Spanish, morirse por algo literally means "to die for something," but people use it every day to say they are dying to do something. Right off the bat, he sings, "Me muero por robarte un beso" (I am dying to steal a kiss from you), hoping that losing his mind for a second will finally make his heart lose its fear. Instead of rushing headlong into a frantic romance, though, he slows way down: "Me muero por amar despacio / La prisa no nos debe apurar" (I am dying to love slowly / Hurry shouldn't rush us). He treats life as a road trip you should actually enjoy rather than sprint through.
From there, Rivera leans all the way into the literal drama of his own metaphor. His chorus makes a giant, theatrical bargain: "Si me muero... De amor que muera / Y que cuando muera / Que sea de amor por ti" (If I die... let it be of love that I die / And when I die / Let it be of love for you). It is delightfully over the top. He talks about stuffing his memory full of stargazing ("Tus ojos y una luna llena" [Your eyes and a full moon]) so that when his time is up, nothing was wasted. He even asks God to rewrite the rules of time itself and turn whatever days he has left into forever ("Pedirle a dios que cambie el tiempo / Y que lo vuelva eternidad" [To ask God to change time / And turn it into eternity]). It turns an everyday phrase about craving a kiss into an all-in promise to love someone until the bitter end.
