I've started testing 0.7.2-197-g61ffb7d9 coming from 0.7.2, and so far so good.
More precisely :
Collection seems fine, so and does adding the Rating column. I think I had to add, remove, then add it again one time for it to work fine, but I may be mistaken.
I don't have any personal playlists so I cannot tell.
I have two "Jamais écouté" (= "Never listened") default playlists, but one has "Listening count >= 0" as criteria.
Where does "Most listened" playlist takes its data ? I'm pretty sure I reset my collection in the past (when trying to troubleshoot duplicates issue) but it still show tracks I like and often listen to, but not necessarily the most listened to.
Other default playlists look fine.
My only "Not rated" smart playlist works fine too.
Sorry to hear about your health problems, I hope you get better.. I always heard that back pain is one of the most painful and annoying issues someone can ever have.. take care of yourself honestly, health it's the most important thing.
Sorry for being late to the party, but I've just become an sponsor, I know is not much but I decided to support you on a regular bassis even with such small amount, it's all I can do for the moment. Your project is really important to me, Strawberry is basically along with Clementine (although it seems to be stalled) the only good and viable Subsonic desktop client for macOS, and I would like to continue using it for a long time
