Recognized Playlists containing Subdirectories are emtpy

that's exact what is working for me and what I tried to mention above

/test/1 - Stand By Me.mp3 => means, "1 - Stand By Me.mp3" is located directly under "test" => the playlist shows the song correctly
/test/Shadow of the Colossus Roar of the Earth/1 - Stand By Me.mp3 => means "1 - Stand By Me.mp3" is NOT located directly under "test" but its album name => the playlist does not show the song
