I work with a lot of audio books previously on cassettes.
I have converted them to MP3 and dropped them in the library.
They fail to get much in the way of meta data, but I have a neat folder layout and they are numbered.
I need to be able to select play a folder via my android phone in order to be able to queue up the stories in a sensible way. (Some stories have 200 or so tracks)
Alternatively I could create playlists for each audio book, but it takes forever adding tracks one at a time, I am looking for an easy ways to add whole folders at a time.
Also, when the android app looses connection and you need to tap retry connection, it looses your progress. (Still on the server… but the app no longer shows it.)
