~/Music/ directory is actually full of "empty" directories I want to clean. I say "empty" because this directories actually contain files, some contain old cover image files or
I want to recursively delete all of these directories that don't contain any music files inside or other directories inside.
For example ~/Music/Audioslave/ contains a lot of directories with album names and no music files, but I don't want to delete it because inside there are the music files. I want though to delete ~/Music/Audioslave/oldalbum/ if the oldalbum directory doesn't have nor music files nor other directories inside.
