CustomFilename
Allows the filename that will be grabbed (cached to the AudioDirectory) to be named according to the corresponding fields using these values: %TRACK% - %ARTIST% - %TITLE% - %ALBUM%.
This particular syntax results in a filename like '1 - The Beatles - She Loves You - Meet The Beatles.wav'.
%TITLE% is a mandatory value!
Possible values: %ARTIST% , %TITLE% , %ALBUM% , %TRACK%
Default value: %ARTIST% - %TITLE% - %ALBUM%
