I don't hate the songs, but yeah, the production's notoriously terrible, up to the degree I actually managed to forget about it, because ever since the album came out, I always played the bootlegged Guitar Hero version.
(you know it's bad when this comparison is on the wikipedia page of your album
)
I mean, this is almost a Vlado Meller-level botch job, I remember the original version being almost unlistenable in headphones.
That said,
Dance of Death comes ... if not
close, then at least half-way, for similar reasons (
here somebody did a comparison of the waveforms of their albums and - surprise surprise - DOD looks almost like a pure block)
EDIT: I know this is an example of mastering, not production as such, buuuuut the producer should be responsible for that as well (and usually is, see the brickwalling of nearly every Rick Rubin-produced album)
