Maybe there's been something useful in the trolling example thread:
There was an artist mentioned, named "Pole", whose music was claimed to be hard to encode. I listened to some (lossy compressed) samples. For example, there's loud crackling noise, like taken from a dirty LP, switched on and off, used as "drums" ... . Compared to the problem samples I know, I guess that this music could be a worthy source of problem samples indeed. I think the more problem samples you know the better - right?
So my questios: Does anyone have songs of this artist (and noticed encoding problems)? Or do "Pole" test samples even exist already?
