This works great! So, so nice to just be able to directly work with the database.
Here is the key new script, that dumps out all the playlists to plain m3us (just relative paths) in the same directory.
I am also very happy to have this script as it means there is now little risk in using Strawberry - I can make my playlists there and if needbe, dump them back out to the plain m3us I use with ncmpcpp.
