Amazon Music Player is great for subscribers, but for those who don't want to buy a monthly subscription and/or just want to buy mp3s directly (play songs on more quality music apps) the app is changed for the worst. Any purchased mp3s are now hidden files and are unable to be played other than on the Amazon Music App. I believe that has changed since the new update on late February. Again, not a problem for those who choose to subscribe, but I am one of those above.
