Most of my downloaded songs recently were removed and then redownloaded. This is really annoying and shouldn't happen. I have seen posts back to 2013 saying they have the same problem. I checked the reasons why this may occur in the help section but still can't see why it is happening to my files. I don't have any other devices that have gone off line or downloaded. Does this happen every time the app updates? I would like to recommend Spotify but can't while this occurs.
