I downloaded Coma White from Mechanical Animals some time ago, and it is quite a good song. Didn't Billy Corgan have a hand in its preduction. That could be the reason why its better, because Billy Corgan is awesome.
Also, The Everlasting Gaze on Machina is very Mansony, as is a live recording I found of Bullet with Butterfly Wings. I think Bill Corgan admires Manson in quite a big way.
And isn't Holy Wood later than the three I have at the moment?
No fucking way. That's a laughable statement. Manson has only the power to rip off and copy.
He is Alice Cooper V2.0. He steals all his industrial elements directly from NIN and no doubt does the same with Corgan. When BC produced Coma White he would have rejigged added and tinkered until it was his beast and a decent song.
It is interesting to note Trent Reznor's actual involvement in Manson's career. Going from very good friends, to "enemies", and back to good friends. So it isn't surprising some of it echoes a bit of the type of production you would hear from NIN. On top of that, Trent isn't necessarily an original product himself, but that's another topic.
As for Corgan, pishoo.
Manson and Reznor are both respected in my book owning one cd by the first (Greatest Hits S.E.) and nearly the entire catalog of the latter (I'm only missing a few Halos).
