I used to love this app because I could buy music and download it to my phone to play on my phone's music app, where I have all my playlists. However, since very recently, I can no longer play music bought on the Amazon Music app anywhere except in the app, itself. This is very frustrating, since I purchased a lot of music over the years from them. I really hope they are going to fix this. Thankfully it hasn't affected the music I downloaded prior to this change.
