I have cleared the cache, I have verified that there is only one copy of the album and thus songs, I have rescanned, I have searched the web for everything I can find.
None of it fixes the problem. When I scan the Music folder on my SD Card I end up with duplicate entries in many folders. In at least one case I see that one set shows up with the album art and a proper report of the file type, bitrate and bit depth whereas the second set only shows the time and file format with no album art.
Needless to say, this is outrageously annoying. How do I fix it? How do I prevent it from duplicating entries in some folders when there is only one such folder on the card?
