A lot of standard music players will not mount the folder directly to the machine so you can’t add any music to the players.
If you install SMB4K you will be able to manually mount your folder on a network. Mine is a diskstation so looks like: smb://diskstation.local/My Data
Once this has been mounted in SMB4K you will see that there will be a new mount name: /home/stuart/smb4k/DISKSTATION.LOCAL
you will now be able to add this folder to a linux jukebox like: silverjuke
sudo apt install smb4k
sudo apt instal silverjuke
