Well, I don't know that Amazon is using MP3. LIke you, I have MP3s available for the physical CDs and they show up in my Amazon Prime Music Library. In fact, it is more likely that they are using AAC. Like Apple and other on-line streaming sources, if Amazon is using AAC they probably are using 96Kbit streams which perform about the same as MP3. Full "transparency" requires 128Kbit streams and even with those there is some loss.
I noticed the fades during sax or clarinet solos with backup instruments - just the sort of environment that would require high frequencies for good reproduction as the sound waves from different instruments combine. I haven't tried it yet, but the definitive test is bagpipe music - no lossy codec can reproduce bagpipes accurately.

Here's why: I use iTunes Match which for <$30/yr stores all your music in their cloud. BUT they also "match" the music if they can, and if so, gives you a higher quality version. Indeed a standard trick is to delete the mp3, then download it from iTunes Match, which gives you the higher version. Alas, no choice in format, its AAC. For Apple users, Amazon even has an option to auto load its download into iTunes, thus automatically converting to high quality AAC. I buy most of my music from Amazon in digital format, thus get their mp3 and it auto-converts to AAC. This is all in Apple's interest: they store one copy, the AAC they get from the music industry, and "share" it with all users of that album/song, vastly reducing their storage requirements. It would be interesting to see, in fact, if the Apple AAC is really of higher quality than the Amazon mp3. -- Owen On Mon, Jul 7, 2014 at 9:40 AM, Parks, Raymond <rcpa...@sandia.gov<mailto:rcpa...@sandia.gov>> wrote: Yeah, we'll all have to start our music collection all over again. First we collected vinyl, then 8-track, then cassette, then CDs, then local files (MP3 for most but .ogg for me) and now cloud. The sad part is that the very folks who think that cloud is cool don't have any idea of what they're missing. Most cloud MP3 files are lossy - I was listening to Amazon Music's 50 Greatest Jazz songs playlist over the weekend and noticed multiple occasions when the volume faded. That always happened when a musician hit some really high notes whose harmonics get clipped by the MP3 format.
