Hamelin didn't recognize his own recording of some of the ChopGods when they turned up in the Hatto version. Granted, they were tweaked a little, but still, you'd think something would sound a bit familiar.
Yea, this is the weirdest thing, when I listen to another recording of something I've played, if they play it the "same way" I would take notice. That's pretty impressive modification.
I think if they are really "original" in some way, then I think they can be appreciated in their own way, with some caveats of course lol.
