Anyone interested in a pandora client which downloads music and saves in a format that Plex recognizes? I modified Pianobar (command line pandora client for linux) to download a song every few seconds and save it to local drive in a format that Plex recognizes so you can automate populating a music library.
I am working on having the system create playlists automatically, also. It saves the pandora song list and creates an iTunes style XML file that can be imported into Plex.
The source code is available here: https://github.com/balsax/pianobar_plex
This is still in development and not recommended unless you are comfortable using linux command line and compiling source code. A config files needs to be placed in ~/.config/pianobar/config which has save location (google pianobar-save). I will add better instructions if there is interest...
