I guess so
I usually listen to most songs without knowing which country they're from (although in some cases it's of course usually hard not to know, like with Portuguese, German, Italian), and this is one of the songs where I had absolutely no idea, at all, which country it could be. Not the first time it happened with Serbia, I think I also gave them 12 points once when they had a very, very Irish song
Same with Slovenia this time, which for some reason I was absolutely convinced was from Indonesia (with the 'Hir aj kam, hir aj go')
