Edward Tufte would have a field day with the way the diagrams don't entirely explain the conclusion in this piece on the new Metallica album in WIRED. Its sound has been so tightly compressed, apparently, that the Guitar Hero version offers more detail than the CD version.

The mastering engineer blames it on the original files - which, frankly, could easily be the case with a rushed release. And he says he hopes this will lead the industry to turn its back on overcompressed music with no highs or lows.

Seems unlikely. Great music and shit music both sound the same in a 128 MP3 through an iPod, and it's not like Apple gives its users an easy way to record files that would let them hear a difference in quality.
