Totally disagree. You are representing your country, in one of the greatest common arenas of European cooperation and fellowship. It is a bit like national teams. Just because you play for a major league team like Real Madrid or Liverpool, does not mean you will not send your best to the world cup. That England continually fails to provide a good artist or song, adds to the international stereotypical prejudice against British people being prudent, condescending, high and mighty, not participating seriously. Especially when they are pre-qualified, which I also find to be detrimental at best. No, I am not arguing that the other countries send their very finest and most established artists, but that they at least make a much grander effort, by whom they audition and how people vote. "Embers" was truly uninspired and woeful. On the contrary to say Ukraine, which was very much Eurovision-like in its weirdness, but was still entertaining and powerful in how it was connected to the country's roots, and yet innovative and memorable. Or Finland, who stick to their classic rock-inspired spirit of nature every year. That is Eurovision for me, not completely forgettable songs like Ember.
TIX was there primarily because of his status as a super popular Norwegian artist. His background is that since 2015 he has been making party music for the college phenomenon in Norway called "Russ", where graduating high school pupils spend the last month of school wearing uniforms, excessively partying and letting go of all social boundaries. His songs have been super catchy, but also incredibly sleezy as they should be for this cultural thing. Since then he has the last years opened up about going through serious depression due to compulsive obsession disorder, Tourettes and tics (hence his artist name TIX) and suicidal episodes, and has converted completely into playing motivational songs for people in need. He has transformed from someone high school aged fans love, to a really wholesome character that everyone cherishes and roots for. Hence he was voted to the finals, unfortunately coincidentally with his worst song of all time, that was dreadful in most ways. Ironically if he had used his old music self, much more fitting the profile of Eurovision, he probably could have won.
Examples of his past music more befitting.
And his more typical parody-themed sing alongs which would undoubtedly also have gotten a lot more points.
