Windows Media Player reset itself out of the blue between the time I closed it one day and opened it the next day. Wiped out my play counts, replaced all my carefully corrected artist names with whatever metadata is attached to the MP3 ("VARIOUS ARTISTS" IS NOT A SINGER OR GROUP, YOU JERK. Neither is Avicii.), and is generally earning my wrath. Why did it do this and how can I stop it from happening again?
