Mastered for iTunes: Rolling out on a worldwide basis, Apple is now featuring songs and albums that have been specifically mastered for the iTunes Store to provide the best sound quality for the format.

Was looking through a recent 'Mastered for iTunes' thread on Slashdot. Anyway, there was this rather interesting link that discussed how one particular mastering engineer, Andy VanDette, has created masters of Rush albums specifically designed to be encoded into AAC for the iTunes store. From the article:

QUOTE
"Mastering for iTunes was a different challenge," VanDette told Ars. "You can't get around it—when you throw away 80 percent of the data, the sound changes. It was my quest to make the AAC files sound as close to the CD as possible; I did not want them to be any more loud, hyped, or boomy sounding than the CD."

...

"For iTunes mastering I focused on making up for the losses created by the iTunes AAC algorithm. Generally, I heard changes in level, bottom, top, punch, and imaging."


The main problem I can see with this approach is that if, in the future, Apple does start to release lossless material or re-encodes the material using an updated encoder the resulting files will quite possibly sound a bit 'peculiar' I guess.
