¡Qué bonito! ¡Qué sentido! I love these old-classic songs. Thank you for bringing them to possible popularity.

Opinion:
In the first stanza last line, I, personally, would say:
"in my dreams, I over flow you with blessings", or "I over flow blessins upon you".
At the end, wouldn't you like "to die" instead of "my life"?

There is an anusual expression that gives special feeling to the lyrics.
The singer says, "has muerto todas mis ilusiones". We know "muerto" means "dead". The translation uses the appropiated form, "to kill". Although correct in regular language, it takes away that special feeling I was talking about. Could you figure out a way to say it closer to the original?

Thanks again

The original rendition is sung by a man. It says: "Contigo me voy mi negra". In those days, in Cuba, "negra" was an affectionate way to name your woman. (I don't know whether it will be allowed today).

Male or female singer, I like "have let die all my illusions".

And Valeriu, you are wright, I have heard "santa". That,s the replacement for the original "negra".

Apreté el botón. Creí que mis comentarios favorables serían suficiente, y fíjate que le di las cinco estrellas!í

The phrases, mi negra/o, mi santo/a, mi chino/a, etc. are all terms of endearment in Cuban jargon. Not sure if the same in other Latin countries but I can only speak for my Cuban heritage. I don't know how these phrases were originated, but they do not have any racial or ethnic connotation when used affectionately. Cubans address these phrases to any person, irrespective of race, age, gender, relationship, etc. I grew up hearing my dad call me "mi negra" affectionately and my parent's endearment to each other was "mi chini", with no allusion to race or ethnicity. It is just a colloquialism of the Cuban culture. The words are personalized by adding "mi" (my), i.e., mi corazon (another endearment not to be taken literally as my heart, but rather my love). In this song, whether mi negro or mi santo is used, it has the same sentiment.
