Hum... only short parts in various languages (Swahili, Russian, Lakota, ...)
Not counting the "Love Song" by the German musician Bodo Wartke (every verse has the same simple text, but in many different languages. Finnish sounds really great

)
Hum... don't have the faintest idea which Romanian song you are talking about. Actually I have never heard a song with Romanian lyrics, so I can't know.
The next poster has not known that the language Lakota exists (I had to look it up myself...)
