in build 2065 mediamonkey seems to assign rating 0 if the properties of a track are changed while the track has no/unknown rating. To reproduce
- Take a track with rating unknown
- Open the file properties for the track and edit any setting other than the rating. So far I tried disc #, date, artist, title, grouping, publisher and custom 3
- The track will now have rating 0
I couldn't find a way to change the rating back from 0 to unknown, so maybe this is actually intended behavior, not a bug. At the very least it seems to be a visual inconsitensy as some tracks show 5 empty stars while other tracks don't show any rating at all:
Also, related to this thread, this only happens if single tracks are edited. If the properties of multiple tracks are edited at the same time, their rating isn't changed.
