I don't have any issue listening to it in terms of its sonic quality, unlike Death Magnetic, but I can understand everyone's criticism of both that and the music itself.
I hate the brickwalled sound of DM, too. That's why I listen to the GH3 or Deceifer Remix. Much better sound. When the album came out, I was absolutely thrilled with the songs themselves. To me, it was the best they'd done since AJFA. You could actually hear that album in some of the songs, too. However, even taking out the snare, St. Anger, to me, was just too abrasive-sounding. I totally get that, as they say, timeline is everything. When that album came out, I was 30 years old. And, it just didn't really fit in with me, at the time. Still doesn't. I'm glad that there are music fans with whom the album resonates. It just falls flat with me.
I was also 30 when St Anger was released, funnily enough.
Yes, I've had the Death Magnetic GH3 remixes* since release. I just irks me that even all these years later, if we want to hear Death Magnetic at its aural best, we have to listen to an unauthorised version. I know there's a debate regarding it not being the artist's true vision (hi, Stadler!) but yeah, when the original is as fucked as it is, I don't care about the artist's original vision. And I also can't justify Lars' cloth ears (if memory serves, he pulled an Iraqi Information Minister move and said he couldn't hear what was wrong with it).
*for anyone who doesn't know, they're effectively remixes rather than remasters as such because the creator had access to what were basically stems taken from the Guitar Hero files. Those stems were effectively unmastered so hadn't been subjected to everything being slammed to 11 and another 10db on top of that. Since Death Magentic was released concurrently in shops, online and in Guitar Hero, it meant the so-called Guitar Hero 3 Mix/Version/Remasters etc instantly became very popular. And yes, the Guitar Hero series was a really big deal back then!
