Once again Balkaneuro comes to the rescue! Thanks a lot for the references. I did find some other songs by Rovena on Studentet.info! Haven't had the time to download them yet, but I will soon. Poni is one of my absolutely favourite artists, so I guess I will appreciate Rovena too. Nertila Vreto is also a golden tip! I saw some video's of her songs on YouTube. She's great! I knew that song Lala Gjoni but I thought the girl was just a one-time sidekick for Nazif Cela (I know HIM from the song Vajseza Vlora - very nice too).
I am absolutely sure that the man in Rovena's en Poni's videos is NOT Nazif Cela (Nazif is smaller and of a more slender build), but never mind, my curiousity is satisfied for the moment. And if he is really important, I will meet his name elsewhere eventually.
