Backup - Substreamer does a few things that are outside what the subsonic API accomodates (MBID Overrides, Listening history and analytics) to deal with this we need to keep some detail locally with your app and we don't want it to be lost if you have to re-install the app or get a new device (No one wants to break their listening streak!). This data is automatically set to be included in your devices native cloud backups.
