Using Mp3tag to write any WMP rating tag of 1-5 immediately shows in WMP 12.
But if I write either "blank" or "0", WMP continues to show the last remembered rating, even after restarting, though Windows Properties is correctly showing 0 stars.
WMP is obviously holding on to a rating in its database.
The only way to get a 0 rating showing again in WMP seems to be to do it in WMP.
Is this a WMP bug?
ALSO, when you rate in WMP, you lose some of the extended tag values - I was keeping an eye on the DISCOGS_RELEASE_ID, but it reverts to "ISCOGS_" after using WMP to rate.
I have WMP set to "Maintain star ratings in files" and "Write media info changes to files".
