Can't control spotify via command line

[Valeyard1]

Recently I started to use Void Linux, and one of the first things that I did was download spotify, so I downloaded it following theses steps:
Void Wiki Spotify

Every time I start spotify, this weird message shows up:

I can listen normal songs, but I'm not able to control it by command line, I've tried every command to make it:

1:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause

2:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Pause

3:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Play

4:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Previous

5: 

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next

However, none of them work, and gives me the same output:

Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.mpris.MediaPlayer2.spotify was not provided by any .service files

So i've tried to do a lot of things:

1. First thing, of course, I checked if there was a dbus service running, so i've typed:

ps aux | grep dbus 

And the output was:

2. Enable dbus in Void linux:

ln -s /etc/sv/dbus /var/service/dbus

3. Start a dbus service:

dbus-launch

4. Some guy on freenode in the #linux channel, said me to see if this variable was empty: $DBUS_SESSION_BUS_ADDRESS. So i typed:

echo $DBUS_SESSION_BUS_ADDRESS

and, indeed, it was empty, so he told me to type the following command:

eval `dbus-launch`

Then, the $DBUS_SESSION_BUS_ADDRESS variable wasn't empty anymore:

echo $DBUS_SESSION_BUS_ADDRESS

Output:

unix:abstract=/tmp/dbus-lCHj4CqJM8,guid=c84e7f8a483e82ea219cefd15a9b2c16

But, none of the above attempts worked. What can i do to control it via command line?
