This is statistics, not the hate.
Well, if it were pure statistics, you wouldn't have used the word "bland", would you?
Most countries have had bad runs at Eurovision in the last couple of decades. Denmark have had one since the epidemic, countries like Portugal and Switzerland had some disappointing years before that, Norway is known as the country with most last places, Germany in general has done badly for years, the UK and Spain as well. It can go up and down, sometimes it's just coincidence. For instance, if you have a national selection, the voters can simply choose the "wrong" song.
In the case of Denmark, there is a correlation between the start of the bad run and the organizer's (DR's) decision to focus more on Danish written songs, young inexperienced Danish singers, and songs performed in Danish. At the same time, the priority was to have even more Dansk Melodi Grand Prix on DR's radio. These decisions seem to have resulted in selections with slightly less Eurovision appeal and less professionalism. And for example, songwriter Lise Cabble, who is by far the most succesful Danish Eurovision songwriter, hasn't participated much in recent years, and when she did - with Silver Bullet, a pre-show favourite - her song was destroyed by weak vocals.
Is it wrong by the Danish organizer to have stopped the import of Melfest left-overs? I don't think so. I think the national finals should be as national as possible (like in sports), and I don't like it when Germany "buy" a Dutch singer for their contest. I also think that the nations should choose the songs that their populations appreciate and not leave the decision to some "experts" who believe they know "what will work" at Eurovision.
I'm sure Denmark could do better if the songs were taken out of the context of the public radio, and if the national selection was turned into an internal one, but I think it's perfectly okay that DR want to use the contest for more than just a couple of TV shows in February and May.
Besides, I don't get why it's so interesting to talk about what countries are sending bad or "bland" songs to Eurovision. I mean - I don't think it's great that Norway and Sweden have failed to do well in football in recent times. I believe they are doing what they can to improve. They may have a limited base of talents - there are many reasons probably. But I wouldn't ridicule them for the lack of success. And I don't think countries that have underperformed at Eurovision deserve to be the subject of criticism solely because of that.
In fact, if you take Eurovision, some nations have pulled out after a run of NQ's. Is that cool? No, it's not. It's a pity.
