v18 - extra fanart and MusicVisualisation what am i missing ?

i have setup extra fanart Variables.xml and have it working with the right code
$INFO[ListItem.Art(clearlogo)] or $VAR[BannerVar]  see 341988 (thread)






works on all screens but MusicVisualisation

i can use the $INFO[Player.FolderPath]image but the artwork needs to be in music folder


is there a way to get artwork link from Artist Information Folder ?
