Foobar2000 Command Line

I am trying to control foobar2000 from the command line, specifically I would like to select a particular playlist, to then play songs from.

I've been using this helpful wiki page: http://wiki.hydrogenaudio.org/index.php?title=Foobar2000:Commandline_Guide

This is the command I am currently using.

foobar.exe /command:"My Playlist"

I can get simple commands like /play to work, but no "/command" commands? Any ideas and thanks for the help. :D
