Loudness Wars

I was in the studio today recording vocals for a couple of our new songs. While I was there Matt (sound engineer & producer) was talking to me about how CDs have gradually become "louder" and "louder," due to standard industry recording and mastering processes. Anyway, this Wikipedia entry on the "Loudness War," as suggested by Matt, is a pretty educational read. Of course, I still don't completely understand the entire thing...
