Awesome WM config for multimedia keys to control Spotify

rtc.lua

awful.key({ }, "XF86AudioPlay", function () awful.util.spawn_with_shell("dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause") end),
awful.key({ }, "XF86AudioNext", function () awful.util.spawn_with_shell("dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next") end),
awful.key({ }, "XF86AudioPrev", function () awful.util.spawn_with_shell("dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Previous") end)

WOOO

I've wrote a helper function:

-- {{{ Spotify
function sendToSpotify(command)
  return function ()
    awful.util.spawn_with_shell("dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player." .. command)
  end
end
-- }}}

-- {{{ Key bindings
globalkeys = awful.util.table.join(globalkeys,
    -- {{{ Spotify 
    awful.key({ modkey }, "s", sendToSpotify("PlayPause")), --  XF86AudioPlay
    awful.key({ modkey }, "d", sendToSpotify("Next")), -- XF86AudioNext
    awful.key({ modkey }, "a", sendToSpotify("Previous")), -- XF86AudioPrev
    -- }}}

There is some way to make these keys work for Spotify and Rhythmbox?

Is this broken in the latest release of Spotify?

Works for me with

awesome v4.1 (Technologic)
 • Compiled against Lua 5.3.4 (running with Lua 5.3)
 • D-Bus support: ✔
 • execinfo support: ✔
 • xcb-randr version: 1.5
 • LGI version: 0.9.1

Check your Dbus support
Try executing only the dbus command dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause

I just set this up on my machine: https://github.com/acrisci/playerctl

Had it working fine on i3wm, working on adding it to awesome right now.
