So far best structure is: folder (Artist - Album) files: folder.jpg Artist - Track No - Track Name.ext from @Nice Monkey : Next to Folder.jpg also Cover.jpg, Front.jpg and artist.album.jpg (=matching the folder name) is used automatically. These are the 4 most common formats widely used. Next to Artist - Track Nr - Track Name also Track Nr - Track Name - Artist is working fine. This with displaying Track/Title on top and Artist below after folder scanning that is. Never put Artist before Track Nr myself as file sorting on Nr always goes correct and is a lot more common.
