I've looked at these examples for a long time, and have concerns that it is another notch up in the loudness wars, except we might already have reached our max? I personally don't like clipped, compressed and high volume audio without full range and sound dynamics. Although I admit is more commercially viable and radio friendly (friendly is a deceptive and relative term, meaning commercial, again), but it still blasts us with crappy sound, IMO.

which is biased (ha ha) in favor of my beliefs and taste, and if you can take more scientific explanation, invest some time and consider this explanation with some technical stats thrown in for our experts... http://www.youtube.com/watch?v=8EgamkLkXW8
