Hi,
I think I identified the problem. Finally, it has nothing to do with analyzing files but with the lyrics.
When lyrics are added to a file, it creates a copy. At the end of the song, the original file is put into the recycle bin, with a (1) suffix. And the new file replaces the old one.
Is there a way to avoid the behavior, please?
EDIT : problem still persisting on last MC28 version.
