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.
Carlos Rivera's "Me Muero" is a hugely romantic and dramatic declaration of love. The title itself, which means "I'm dying," is used throughout the song to show just how intense his feelings are. He starts by saying he's desperate for a kiss, singing, "Me muero por robarte un beso / Y porque pierda la razón" (I'm dying to steal a kiss from you / And to lose my mind). He hopes that going a little crazy will give him the courage to finally act on his feelings.
But this isn't about a rushed, fleeting romance. He wants to take his time, because "la vida es un viaje / Y yo lo quiero disfrutar" (life is a journey / and I want to enjoy it). The song then gets a little philosophical, wondering what happens after we die and what's left of us. His conclusion? Memories. He wants to fill his memory with moments of this person so that if he dies, it's from an overwhelming love for them. The chorus makes this grand statement perfectly clear: "Si me muero, si yo me muero / De amor que muera / Y que cuando muera / Que sea de amor por ti" (If I die, if I die / Let me die of love / And when I die / Let it be from love for you).
