It was perfectly fine before they "updated" the app, but now I find it useless. I have literally spent hundreds of dollars buying music on Amazon. After purchasing through Amazon, I'd have to go to Amazon Music to download the music to my phone. Since doing the update, I can no longer download music that I purchased to any device. Since the update the only "download" option I have is to download for offline listening. I've bought 5 songs that I can't download. I'll have to do business elsewhere.
