I think Norwegians had their overdose of "Hallelujah" seeing as four Norwegian artists (Kurt Nilsen, Espen Lind, Alejandro Fuentes and Askil Holm) got together and went on tour, and "Hallelujah" was one of the songs they played. I think the person who wrote the comment just thought that it was a bad choice because he's already heard it a couple of times. but I guess Norwegians don't really know that Damien has been singing "Hallelujah" for way longer than those guys.
I thought it was a beautiful way to end.
