Problem with Multidisc Albums

[simoncn]

If you want to keep the files and folders as you have them currently, you should add an AlbumArtist tag to all tracks of this album. This tag can have any value. For example, it could be 'Berliner Philharmoniker & Wiener Philharmoniker' or 'Jacqueline du Pré' or 'Various artists'.

If you are willing to change the folder arrangement, you can combine all 4 discs into a single folder and leave the tags as they are currently.
