	mympd = lain.widgets.mpd()

	| |/^\_/^\| Now playing                                  |
    | |\ O O /| Cannibal Corpse (Hammer Smashed Face) - 1993 |
    | | '.o.' | Hammer Smashed Face (Radio Disney Version)   |
	| +-------+                                              |

Finally, you can control the widget with key bindings like these:

    -- MPD control
    awful.key({ altkey, "Control" }, "Up",
        function ()
            awful.util.spawn_with_shell("mpc toggle || ncmpcpp toggle || ncmpc toggle || pms toggle")
            mpdwidget.notify()
        end),
    awful.key({ altkey, "Control" }, "Down",
        function ()
            awful.util.spawn_with_shell("mpc stop || ncmpcpp stop || ncmpc stop || pms stop")
            mpdwidget.notify()
        end),
    awful.key({ altkey, "Control" }, "Left",
        function ()
            awful.util.spawn_with_shell("mpc prev || ncmpcpp prev || ncmpc prev || pms prev")
            mpdwidget.notify()
        end),
    awful.key({ altkey, "Control" }, "Right",
        function ()
            awful.util.spawn_with_shell("mpc next || ncmpcpp next || ncmpc next || pms next")
            mpdwidget.notify()
        end),

where `altkey = "Mod1"`.
