This Should Really be called Optimized for iTunes.
Part of the reason for this proposal, is that an average Pop Release,
when run through the afClip analyzer, show thousands of points where
clipping will occur on playback.
This will come as no surprise to most professionals who listen to iTunes
files.
This new methodology gives us an objective measure of the amount of
distortion that gets added during the mastering of most modern music.
Hopefully this will be an incentive for mastering engineers not to
master so hot, and thus move back to the days when mastering was judged
on quality and not how loud you could make it.

Cheers

The best way to think of lossy encoding is as really smart dithering
that tucks a lot of quantization noise away into parts of the waveform
where it can't be heard. Excessive signal processing, limiting and
saturation simply leaves  lots less space to hide the artifacts.
Excessive levels will clip the filter bank that is an integral part of
the process making things even worse.
