I have been using the Streaming Source for a bit here and it is seemingly working very well. There is an oversight that is missing, in the directory there is no option for "description" which at least in Icecast is a standard in it's metadata. It just outputs "Unspecified description" to the server.
Another thing that would be nice for streaming radio is giving multiple options in the Adverts/PSAs. For example being able to have it randomly choose a file from a folder to play every x amount of songs. Or for more advanced usage being able to chain 3 or 4 tracks from different folder/playlists, for example a file from /news/, /weather/ and /commercial/ folders every hour on the hour.
