As if this was an actual surprise to anyone who’s heard the album, Metallica’s lastest album sounds like shit. That is to say, the audio itself is garbage, not the songwriting (for the most part). I didn’t comment on this in my review, as complaining about audio compression these days is akin to complaining that the sky is blue.
Anyhow, [Wired](http://blog.wired.com/music/2008/09/does-metallicas.html) has a great piece on why the albuim sounds so terrible. It’s a fascinating read, if I may say so. Just as interesting is the discussion of why the “Guitar Hero” version of the album sounds better than the CD. Yes, you read that right.
