A small and simple music player for the GNOME desktop Loudhailer is an XMMS-like music player meant to integrate nicely in the GNOME desktop.
Its main interface is a playlist that is populated by drag and drop from your file manager, so it is not intended to be a library based player like Rhythmbox or Muine.
Loudhailer is written in C# and GTK# (runs with Mono) and uses GStreamer (part of GNOME) as a back-end for playing music. The interaction with GStreamer is done via GST#, a C# wrapper library. The GST# dll is included in the distribution files since it is not widely available yet (current svn of GST# does not work with Loudhailer)
