Install git if not already installed:

sudo apt-get install git

# https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-pirate-audio

#This will install python3 pip,wheel and pirate audio modules
#Then add mopidy apt sources and install mopidy including mopidy-spotify
#Then install mopidy-iris web interface and Pirate Audio plugins
#And create system service to autostart mopidy

cd /usr/src
sudo git clone https://github.com/pimoroni/pirate-audio
cd pirate-audio/mopidy
sudo ./install.sh

Alternative web interface:
https://github.com/pimusicbox/mopidy-musicbox-webclient

#Removing mopidy spotify plugin and bluetooth support

sudo apt-get purge mopidy-spotify
sudo apt-get purge bluez bluez-firmware
sudo apt autoremove

#Display will show ip and default mopidy port :6680 for web interface. Iris web client needs to be selected

#Edit Mopidy config
sudo vi /etc/mopidy/mopidy.conf

#file section change
media_dirs = 
    /media/music
    /media/network

#add to http section
enabled = true
#port = 80 #issue with mopidy user and ports <1024
zeroconf = Mopidy HTTP server on $hostname:$port
default_app = iris

#change in audio section
mixer_volume = 20

#add iris section:
[iris]
enabled = true
country = GB
locale = en_GB

sudo mkdir /media/network
sudo mkdir /media/music

sudo apt-get upgrade

SMB mount the manual way (/etc/rc.local or /etc/fstab):
#Note experiment with rsize=61440 option and/or use nounix mount option

sudo mount -t cifs -o ro,username=media,password=media,uid=1000,gid=1000,vers=1.0,cache=none //192.168.1.6/music/beets2 "/home/mopidy/FOO/"
