error in playlist.rb method move

[msym]

hi, thank you for this gem
i got error when try to move song in playlist
there are not enough params (songid and songpos) in @mpd.send_command

def move(songid, songpos)
- @mpd.send_command :playlistmove, @name
+ @mpd.send_command :playlistmove, @name, songid, songpos
end
