Adueñado comes from the verb adueñarse, meaning 'to take possession of' or 'to make one's own'. It's a strong and evocative word that goes beyond simply 'having' something.
In the song, the lyric "Te has adueñado de mis sentimientos" (You have taken possession of my feelings) beautifully conveys the depth of the singer's love. It implies a complete and profound capture of his emotions, making it a memorable and impactful word choice.
This is a live recording where three acts open the song by introducing themselves before anyone sings a verse. 'Edición Especial y Grupo Firme' announces two of them, and 'Y Grupo Firme, y Banda La Indicada' (And Grupo Firme, and Banda La Indicada) adds the third. Once the actual song starts, the words stay just as direct: 'Hoy te escribí una canción, pa' decirte que yo' (Today I wrote you a song, to tell you that I) leads straight into 'Estoy muy emocionado al tenerte, mi amor' (I'm so excited to have you, my love). No metaphors, no games, just someone telling their partner exactly how they feel.
The hook makes the same claim twice across the song, and it holds up the second time: 'Y es que mi amor por ti' (It's just that my love for you), 'Aun crece más con el paso del tiempo' (still grows more as time passes). He follows it with 'Te has adueñado de mis sentimientos' (You've taken over my feelings) and a flat promise, 'Yo te prometo, no te haré sufrir' (I promise you, I won't make you suffer). By the end the whole room is toasting along with him: 'Salud, salud, salud, plebes' (Cheers, cheers, cheers, folks).
