Famous Russians were often inspired by or used Serbian songs and poems in their works. Tchaikovsky, Rimsky-Korsakov, and Pushkin for example.
Of course others were interested in Serbian music, poetry, and literature as well - Dvorak, Brahms, Goethe, Bartok. And Jewish people have been drawn to the Serbian folk scene and other music from Serbia. What's odd is that the same Jews who enjoy this kind of music often propagandize against Serbs, and for those (Albanians, for example) killing and ethnically cleansing both Serbs and the Roma, whose music has become known internationally through Yugoslav films such as "Underground" and "Time of the Gypsies" and famous Serbian Gyspy musicians like Boban Markovic.
It just looks like to me that some of those Jews (who were once or still) quite interested in the culture are actually cheering on those (Albanians) destroying it.
