what's he singing in the chorus? it sounds like "tebe živím, tebe volím" which in Czech means "I provide (food, money...) for you, I vote for you" but I don't think that's quite the correct interpretation
For me Breskvica is miles above the rest. Zejna being second. Konstrakta and Zorja are non events personally. Teya Dora would be my third pick and while I find the song very pretty it takes a bit to get into it.
But surely there should be a rule again Dusan Kurtic singing his (catchy) chorus during the entire voting process every time they're in the Green Room
