The Windows 8 Music App (XboX Music is not available in my country, and this is the alternative) downloads album art by default. I didn't want the app to show vulgar pictures, so I have disabled the function. The problem is that it has already downloaded a few pictures which I find inappropriate. I'd like to remove those.
Luckily, it seems like the pictures were not embedded to the MP3 files. I believe the Music App handles meta-data in a way similar to Windows Media Player, which creates a dedicated database.
How do I reset the database?
