Jorn didn't write that album!!! Kelly wrote the vocal melodies for the Path of Darkness chorus, Ecstasy Arise, and most of the title track, and maybe more I think. I also wouldn't say some of them scream Devil's Hall of Fame, and the reason for that being if you believe so is that the vocal melodies were written over the same style of chord progression as Finn has his own melodic preference like most musicians.
After Jorn switching his story a crap load of times, whether he was misquoted or not, how much truth to whtat he said, etc... it's pretty obvious he was lying. Not just for that reason but I am sure any artist who wrote material and had it stolen would start up a lawsuit right away, especially if it's a whole album. Now possibly I think Finn did say they had started throwing ideas around but nothing of remotely any significant nature that Jorn wrote was used, that would have mainly been reffering to vocal melodies, which I don't believe were used at all. Also, although Jorn is a great singer but we have all heard stories about his ego and other charachter flaws in sterotypical rock stars. I also seriously doubt Finn would have used any of the stuff Jorn wrote just because of the fact that he is someone who is extremly,deeply passionate about his work; the guy goes to great extremes for song ideas.
In the end, Jorn didn't write Section X!
