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.
