Yeah I guess you're right. But seriously, they should hire someone who actually knows at least a little bit about encoding...a lot of their mp3 albums are supposedly VBR but look like whack-as-fuck mutt rips, some actually are mutt rips and are partially 256 and partially VBR, and they've also been known to sell transcoded stuff before. Some shit man, some shit.
I usually only buy digital through Bandcamp or straight from the label for the same reason. I think anything I have on my computer that came from Amazon is the result of one of their $2 mp3 promotions
