Haven't listened to any, except our own. I like to be surprised. Our, the Dutch, song is decent I must say. The guy is the male part of the duo that would have won a couple years ago but lost because there was some woman from Austria with a beard. Anyway, he'll get to the final again this time, but I doubt he'll win.
And you're right, it is fun to watch even if most of it's usually pretty weird.
