Well, we try to enter songs/artists we think will appeal to Europe's tastes. And mainly fail, because we are so different from them.
It's fairly obvious that our countries usual musical output is pretty decent, and if we entered any of that into the contest, we'd win (If it was actually anything to do with the song).
I love the Eurovision song contest though, because it highlights how ridiculous the idea of integrating Europe is. You get countries who always vote for each other even when the song is rubbish, and you get no one voting for us, even when we have a half decent song. The Eurovision song contest is the best advert for a 'euro-skeptic'.
