When I used the word perfect, I meant it more subjectively. Now that I think about it, I would probably dislike the same things in the cover and the original (for instance, one song sounded like it had too many tracks layered over top of each other, but that's pretty common in heavy metal and is likely something I just need to adjust my ears to after listening to Beethoven for the past couple weeks). Because I'm only listening on a single earbud (the other side's broken and the speaker system is back in Alberta, out of reach until next year), I can't pick out how well things are balanced, etc.
Your last upload is my favourite, followed by "The Trooper" and "Every Time I Die", then "Alteration", but they're all pretty good. I don't suppose you can make the non-downloadable ones downloadable?
