Though, if anyone knows Spanish they can tell that Nelly Furtado's first language is Portugese, she still being very fluent lends her voice to this track by Juanes. Nelly and Juanes' voices intertwine and play off eachother very well. As good artist's should they sing this song with the right tone's and the right emphasis on the right lines. I know that seems lame and obvious but if you close your eyes and listen to the lyrics even if you don't speak the language you can feel the emotion and ferver that these words should be delivered at. I recommend this song to anyone, even if you don't speak spanish, you will at least enjoy their harmony and the melodies of the instruments.
