My point was not personally on Estonia but on people saying he didn't qualify because of bad vocals, while at least three other countries with bad vocals did qualify.
I see where you're coming from.
Personally, I think that Belgium didn't qualify for some reasons (I have mentioned before) - when it comes to the vocals, though.. there are entries in which vocals are more important than for another, e.g. I don't expect a fun song like Estonia to deliver great vocals - but if a song consists of vocal gymnastics and many long/high-pitched notes, head voice (etc.), they should be top-notch (especially when the instrumental is quiet, e.g. in the verses of Belgium).
The flat vocals, mediocre vocals made a very inaccessible and loud entry even less accessible - especially since it's been accompanied by some "agressive" colour-scheme, lighting and aggressive, monotonous beat.
Artists which might have sung worse than Red Sebastion could have qualified due to creating a fun or warm atmosphere on stage or simply, having a more memorable, catchy hook (which somehow make "very good vocals" in vain).
And we all know the vocals aren't the problem, but the problem is countries voting for their neighbour countries.
And here I have to strongly disagree with you. I don't "know that".
Slovenia, Croatia didn't qualify even though they potentially got "neighbours" like Albania, Switzerland, Italy voting in the semi.
We Central Europeans always complain about the bloc voting (which somehow exists, no doubt) but then we see these blocs crumble very often.
Yes, all Nordic entries went through but maybe it's just because all three songs were fun, catchy and memorable?
And let us not pretend that the Nordic bloc always comes into fruition.
Iceland didn't qualify in 2024, 2023; Denmark can't even remember what a Grand Final might look like for some time now and I can still remember the "robbed" fails when the Nordics complained about "bloc voting and so on", when songs like "Haba Haba" didn't make it.
The last time, we saw ALL Nordic countries in the GF was back in 2014. That's more than 10 years ago and we still don't know if

can qualify tomorrow.
We've seen countries with huge diasporas fail in televoting, e.g.

didn't qualify in 2024,

didn't qualify in 2024.
Why did

- another "country with no huge neighbour support" qualify? - They used to fail for many consecutive years in the 00's.
Believe me, Europe thinks of NL and BE somehow "the same way" - I fail to see why we should prefer one of these countries more (and it's even questionable if it translate into ESC votes)
Second, I don't think the eurovision community realises what an impact this non-qualification might have. The NQ is being welcomed in Flemish Press and apparently as well within the Belgian eurovisiondelegation with Utter disbelief, especially seeing which other countries did qualify.
So yes in a couple of weeks there will appear articles questioning whether or not we should continue participating in eurovision or not giving the current economic situation of our country. VRT is a mediagroup that is payed through tax funding of the Flemish Government. We currently have a huge national debt, were other unpopular measures are taken to reduce that debt. Eurovision is payed for by taxes of the Belgian people. Questions will be raised whether we should participate in further editions or not giving we won't win it anyway and if the tax money can't better be spend elsewhere.
I think we can definitly scrap Eurosong 2027 from the list, giving the viewingnumbers of this edition were also not good. If we still participate it will be through internal selection but i wouldn't be surprised if we take a break for a couple of years. Of course that is worst case scenario but i don't rule it out.
I read it with a heavy heart. I don't want to lose another country - especially Belgium - But I think it's quite dramatic to project it on Red Sebastian's "non-qualification".
Let us not forget that you ended up being TOP 10 two years ago (2023). That's not even a long time ago.
The Belgian delegation can't expect Europe to vote for Belgium because "two or three other countries didn't deserve to qualify" (according to whom?? The Belgian delegation and some loud fans from Western/Central Europe?)
I hope Europe's broadcasters will become more stable, financially again but I think that the Belgian delegation simply has to digest the "shock non-qualification" now.
