Jendrik, lol... I don't even know whether he has made music in any professional way before... he just did a youtube-video, applied, and was taken...
Seems a nice guy and the song was not so extremely bad, I would certainly have had him in front of Azerbaidschan, Serbia and some other very trashy rip-off dancepop numbers... But on the other hand, if you have a safe spot and don't need to go through the semi-finals you could at least make a decent effort to bring a good song... Well, but Germany did win with Lena a few years ago, despite me being annoyed by her singing and thinking the song was average, so one should probably not ask me.
I only watch ESC once in a few years... when I do it always succeeds in drawing me in although it's unbearable on the other hand. I really thought the Swiss guy did a good job, despite some people saying the song was schmaltzy.
