If you're concerned about where your music is going it's true that music you've payed for and downloaded have gone to different location instead of your usual Artist's folders, hopefully you know what I am talking about. By now you've gotten the Purchased Music Folder notification and followed the instructions but you need to stay signed in, keep the app open, download the music and COPY them one at a time to a folder or Google Drive to make them available offline. Hopefully this works for you.
