I don’t think Musicbox does produce a playlist. I have written out how I do it, it’s probably not the most effective but it works. It is written assuming you are using a windows pc and WinSCP - the idea will be the same.
To make playlists.
Playlists are stored as .m3u files.
Open and connect WinSCP
In the R/H Pane (the Raspi) click through until you find the
album you want.
From the top, double click Music – Musicbox -Artist –Album
Make sure tracks are in correct order by clicking on the
‘Name’ option at the top
Click on the Track at top of list
Hold down Ctrl & A on your keyboard to select all tracks
Hold down Ctrl and use mouse to deselect any files not
required.
Right click on highlighted files,
Choose ‘File Names’ then choose ‘Copy to clipboard (Include
Paths)’
To save as an .m3u file
Open a Notepad document on your computer.
Paste the copied file names into it.
To make it tidy do ‘Edit’ ‘Replace’ Type “ (Double Quotation
Marks) into the ‘Find What’ box then click ‘Replace All’
Save this to the Desktop as ‘Paul Simon – 50 Glorious
Years.m3u’ or however you want the playlist to appear.
Go back to WinSCP- if you are still in the MusicBox section
double click on the top folder (with an arrow on it) until you come back to the
Home or Root folder. It should have a folder called ‘bin’ at the top.
Double click ‘var’
Double click ‘lib’
Double click ‘mopidy’
Double click ‘Playlists’
Find the playlist on your computer desktop, click, hold and
drag to the playlists section.
Once in the playlist
section, click the folder next to drop down box and you are offered the chance
to add that path to the list – saves time later when adding any more.
Go back to the web interface, ‘System’ and select ‘reboot’
If you haven’t added any new music it would be worth
changing the* option in setting to not scan each time.
When the system comes up, have a look in the playlist option
and your new playlist will be in there. You need to do the same for each playlist you want.
You can make a mixed playlist of tracks in the same way, and
move items round the list but it’s quite time consuming.
