Around 2012 I got some credits for Amazon Music (or whatever it was called at the time) so I bought and downloaded a couple of international albums. Then I noticed tracks in a single album could have three different bitrates. Not definitive proof that the files were ill-gotten but very fishy.
I purchased an mp3 from Amazon Music, and there was a song that had a glitch in it, like you used to get ripping CDs if there was a problem reading part of the disc. I torrented the same track and the same glitch was there. So either Amazon was using pirated copies or the glitch existed in the actual recording. I guess I'd need to find a physical copy of the recording to compare.
