(Going slightly outside the collection boundaries here)
Australia's entry [1] was my bet for last night's Eurovision winner, but mainly because theirs was the only one I'd actually listened to just prior to the final. After watching the first entries last night Ukraine was the only one besides Australia to stand out musically for me, though I still liked Sound Of Silence better. But listening to 1944 today, at least the official video [2], it sounds somewhat stale. Perhaps their live performance was more vivid somehow? Sound Of Silence still sounds good, as does Bulgaria's entry [3], which I also liked last night.
(Note that I only watched perhaps less than half of the final before going to sleep, and so my comparison doesn't include any of the later entries.)
