This is a little node service I wrote to live on a raspberry pi which is running mpd (music player daemon) and playing audio via an FM transmitter in my apartment.
This is just so I can hit the pi in a browser and go next/back, otherwise it shuffles and repeats forever.
/shows the currently playing song/nextplays the next song/prevplays the previous song
This also supplies a basic one-page "Now Playing" view with next / previous controls, running on port 8080. Customize view.html if you want. The {{ARTIST}} and {{TITLE}} strings in the view will be replaced by the currently playing artist and song title, respectively.
