Ukraine and Malta's entries have been growing on me in the last few days - I think they've both got a chance in the contest! I haven't listened to the entries enough to separate them all yet, but my top 4 is probably something like:
1. Slovenia
2. Ukraine
3. Malta
4. Australia
Also, after a quick flick through some of the rehearsal videos I've found myself thinking Armenia will grow on me a lot when I watch it live on the night (just as they did in last year's Junior contest). I'm not the biggest fan of the song or the genre, but the kid can really sing, he owns the stage, and those background LED effects are pretty spot-on.
