Adueña comes from the verb adueñarse, meaning 'to take possession of' or 'to become the owner of'. It's a strong verb that implies a deep and complete control or ownership.
In this song, the singer uses adueña to express how the woman has completely taken over his thoughts and feelings: "Que se adueña de mis sentimientos" (She takes possession of my feelings). It's a powerful way to convey being utterly captivated and controlled by love.
Get ready for a passionate confession! Binomio De Oro's "La Dueña De Mi Suerte" is all about a man completely consumed by a love he knows he shouldn't have. He's ready to "publicar estos amores aunque se me caiga el mundo" [publish these loves even if the world falls apart], declaring that he'd give his life for her.
He admits he has other people in his life, but this woman is always on his mind. He says she "me roba el alma solo con un beso" [steals my soul with just a kiss] and that her embrace makes him "olvide el mundo" [forget the world]. It's a powerful, almost desperate declaration of love, even if it means facing a "condena" [condemnation] or "infierno" [hell]. He's willing to risk it all because she is truly "la dueña de mi suerte" [the owner of my luck].
