Joolz,
I saw LEB I SOL is put under Macedonia as country. While technically correct, they are first and formost Yugoslavian band, they belonged to Yugoslavian scene up to 1991. So I would suggest to put it back under "Yugoslavia". Many people who would like to search for info about Leb i sol (or any other exYU band for that matter) will do so having in mind exYugoslavian music scene.
However, their leader, Vlatko Stefanovski solo albums can be put under "Macedonia" because historically they belong to the post 1991 period when Yugoslavia was no more. Be aware that he is listed under "FYRO Macedonia". This is official name but it sounds really rediculuos, and nobody looking for Macedonia would go under letter "F".
so I suggest you put Stefanovski under "Macedonia" and Leb i sol under "Yugoslavia".
Thanks!
