I just donít see everyday people demanding the change to lossless because of this, especially since most people canít tell a 320 mp3 from lossless anyway.
Not that this changes the argument much, but you keep mentioning 320 kbps like that's the popular bitrate. The two most popular online stores that I buy from are iTunes and Amazon.com, and they both sit at 256 kbps for the most part. Apple's 256 kbps might be a wash with 320 kbps MP3. I haven't read enough to know. I doubt I would be able to tell the difference between 256 kbps and lossless for a lot of material. I'd probably have to listen to stuff that was picked to highlight the inadequacies of the lower bitrate. Anyway, I was just nitpicking.
