Egoísta translates to "selfish". While it might seem like a common word, its prominent use in the song's title, "Corazón Egoísta" (Selfish Heart), makes it particularly impactful and central to the song's theme.
In the lyrics, the artist grapples with a moral dilemma, torn between loyalty to an existing relationship and a new attraction. The word egoísta perfectly encapsulates the internal conflict of his heart, which desires what it wants regardless of the consequences for others, making it a compelling and memorable choice.
Have you ever been stuck between two loves? That's exactly where Noriel is in "Corazón Egoísta" [Egoist Heart]. He's already in a relationship, but then someone new comes along and completely throws him for a loop. He sings, "No sé cómo me perdí en tu mirar" [I don't know how I got lost in your gaze], admitting he's totally captivated by this new person.
Noriel is really struggling because he knows it's not smart to mess with a good thing, saying "No es de sabio' cambiar algo seguro" [It's not wise to change something secure]. But he can't help how he feels! He even says his heart is at war with his mind: "Mi corazón es egoísta / Y vive en guerra con mi mente" [My heart is egoist / And lives in war with my mind]. He's caught between telling the truth and breaking hearts, or trying to keep both relationships going. It's a messy situation, and he's asking for luck on his journey, whatever he decides.
