Based on what I've been able to find online, "Nasvalo Sijum Daje" is in the Macedonian Romani language, although I personally cannot vouch for the accuracy of this.
Here's a link to a sample of the song:

And the specific parts of the lyrics that I am concerned with (I don't know if it's the complete song.)
