    #    Info         :
    # The "DestPath" variable holds the path of where to write all the
    # playlists.
    #
    # The variable "MixedDestPath" holds the path and filename for the playlist
    # of the mixed Music.
    #
    # The "Music_Count" variable is then number of individual Music files to be
    # displayed in the menu.
    #
    # Arrays "Music_Name" and "Music_Path" hold information about the Music files in
    # the menu. "Music_Name" is the name of the Music file and "Music_Path" is the path
    # to where all the Music is stored. The number of Music files must
    # be recorded in "Music_Count"
    #
    # The "Mixed_Count" variable is the number of Music files to be put combined
    # into the mixed Music playlist.
    #
    # Just like the "Music_Name" and "Music_Path" variables the "Mixed_Name" and
    # Mixed_Path hold the name and file path of the Music files to be in the
    # mixed Music playlist.
    #
    # This is one of the first scripts I have made. I work as a programmer
    # but as a C# programmer. I wanted an easy way of playing my Music files shuffled
    # while not having to update playlists when adding new .
