Revisiting the Artist and All Artists Index

There is no notion of creating an index for use internally. All indexes are created and shown in response to a user browsing action.

Quote:The AlbumArtist index (corresponding to AlbumArtist and/or Album Artist tags in the files) requires a single value that is consistent across all tracks of an album. If you have another field such as album_artists, this limitation does not apply.

Quote:Your first setting will replace Album_Artists tags with AlbumArtist tags and run into the limitation that AlbumArtist can only have a single value. There is no problem with your second setting.

So decoding these answers is the rule simply that

- The AlbumArtist field (i.e ALBUMARTIST for flac, TPE2 for ID3v24, aART for Mp4) must be a consistent single value for correctly identifying albums
- And therefore using an aliasTag to map album_artists into albumartist would break that.
- But as long as I dont do anything to mess up the value of AlbumArtist fields I can create by own Album Artist type index as I wish ?
