Music Playing Daemon web GUI written in C, utilizing Websockets and Bootstrap/JS. Streams your media to you through your browser. Tries to be as usefully minimalist as possible. Packages for all of the distros you're likely to install it on; compile it on the rest. Only has one dependency, libmpdclient. Requires that mpd be installed and configured beforehand.
