Currently MP3 files that are streamed from Plex server are having some of their metadata removed, such as the Description and Composer tags.

Prologue, the brilliant audio book player for Plex, recently added support to display the audio book Narrator (from Composer tag) and Description metadata. This works fine for M4B files but not for MP3s as the data is stripped out when streaming from the server, even if it already exists in the file metadata.

Please can Plex stop removing this data when streaming, so MP3 audio books work better?
