Audiobook people: If you're curious about how to get your Audible library downloaded for *safekeeping* (and to convert the files to other formats for older players and so on), I highly recommend OpenAudible. It scans your library - even the Audible Originals ones - and downloads them all so you can listen to them wherever you'd like. I use it to get them converted for my Plex library. It's one of those "it just works" kind of apps. https://openaudible.org/
