Hi Stasa and everybody there! Yes, you're completely right. I think one of the things we most love of the languages is that each one is unique. Of course we can always find a translation that can express more or less the same but the magic of the language disappears with the transalation.
However, I am also learning translating English songs into Spanish and I have much fun. I think that translatinig is an interesting activity that helps us not only to learn but also to develop our creativity.
