  // the album link tables.  The only failure point for this is albums
  // that span multiple folders, where just the files in one folder have been changed.  In this case
  // any linked fields that are only in the files that haven't changed will be removed.  Clearly
  // the primary albumartist still matches (as that's what we looked up based on) so is this really

  // case, it will return only things in the album_artist table from the newly updated songs (and
  // only if they have additional artists).  I think the effect of this is minimal at best, as ALL

        For artists these rules are combined because they apply via album and song

        1) Some artists may be only album artists, so for all artists (with linked
           albums or songs) we need to check both album_artist and song_artist tables.
        2) Role is determined from song_artist table, so even if looking for album artists
           only we find those that also have a specific role e.g. which album artist is a
           composer of songs in that album, from entries in the song_artist table.
        a) Role < -1 is used to indicate that all roles are wanted.
        b) When not album artists only and a specific role wanted then only the song_artist
           table is checked.
        c) When album artists only and role = 1 (an "artist") then only the album_artist
           table is checked.
