It would be difficult to find a more divisive figure in Serbia than Svetlana Raznatovic and her come-hither cleavage. But it isn't the cut of her revealing outfits that irks her detractors, nor the fact that her murdered husband, Zeljko, better known as Arkan, was the most notorious warlord in the Balkans. Rather, it is the sound of her music. Love or hate her, few Serbs are indifferent. The songs of Ceca, as Ms. Raznatovic styles herself, were the soundtrack to a decade of destruction that reduced their country to a pariah state.
