Metallica is currently in the process of reissuing all of its old material, freshing things up a little bit and giving fans an in-depth look at each album. We've already gotten Kill 'Em All and Ride The Lightning, but I'm sure the ones fans are most interested in hearing given some lovin' are …And Justice For All and St. Anger, for obvious reasons.
James Hetfield tells Red Bulletin that while the former could use more bass and the latter's snare drum sound pretty much sucks, those records are still what makes Metallica who they are.
There are things I would like to change on some of the records, but it gives them so much character that you can’t change them. I find it a little frustrating when bands re-record classic albums with pretty much the same songs and have it replace the original. It erases that piece of history. These records are a product of a certain time in life; they’re snapshots of history and they’re part of our story. OK, so … And Justice for All  could use a little more low end and St. Anger  could use a little less tin snare drum, but those things are what make those records part of our history.
So who knows what'll happen with the reissues of those albums.
