Polish song: https://www.youtube.com/watch?v=lbNBrfs-vvU has apparently stolen instrumental from song that I am looking for.

It has the same instrumental, rhythm and same post chorus [la la la la la] but is sang in another language im thinking of some spanish/french/ romanian language because i've heard it in some romanian house mix.. sadly they deleted it ages ago and I cannot find it because I don't remember anymore words that are in other language :/. Please let me know if something of this sounds familiar for you, THanks!
