On a scale from 5-10, which I did as the show progressed, and noting the qualifiers with "*":
10 *Turkey - Balkan songs win Eurovision so often because they sound awesome
9 *Sweden - great voice
9 *Iceland - great voice
9 *Malta - great voice
8 *Armenia - nice, but maybe some notes were botched
8 *Finland - standard fare for the finals
8 *Israel - touching but a bit boring
8 Andorra - oops, they didn't make it, pity
8 Macedonia - oops, they didn't make it and kinda generic rock
7 *Bosnia - a solid performance, maybe I should have given it an "8"
7 *Portugal - okay, but maybe this made it in with the help of the judges?
7 *Romania - started out great, but I felt it floundered into mediocrity
7 Belgium - looking good only because of the two acts before (Czech and Montenegro)
7 Switzerland - generic pop rock
6 Montenegro - the guy ruined it
6 Belarus - embarassing
5 Czech Republic - worse than embarassing
5 Bulgaria - like male cats yowling at each other
Turkey was awesome, and I hope they win it, so I can get sick of that song rather than something less palatable.
I think I understand Macedonia's entry. I've been to Macedonia, but I've been to Bulgaria a lot more, and there I know they love 70's and 80's dinosaur rock. If you go to a party there, the music you'll hear will likely be ancient American rock bands. So, I think Macedonia's taste for this just didn't translate to Europe as a whole. It made my cut at "8", but it was unremarkable.
Bulgaria also has a taste for "chalga," Bulgarian folk-pop music, Balkan music, and so I was hoping for something of the same caliber as Turkey's entry. Alas, the Bulgarian entry was a complete disaster. The guy really sounded off-key. In general, falsetto runs from mediocre to horrible, and this was clearly on the horrible end of the scale. I think it's possible that this was a good but difficult song that was ruined by a bad performance, but it's hard to tell through the bad performance. This debacle reminds me of Azis, the bearded transsexual Bulgarian male who is so popular in Bulgaria - they sent him to Eurovision in 2006 and Bulgarians just couldn't understand their entry did so poorly in Eurovision. Although Balkan music rules, Bulgaria is sometimes a little too far off in its own realm in its Eurovision entries.
