'artist' is the artist or even several artists of given track. 'album artist' is the pseudo-artist of whole album. i wrote 'pseudo' because it usually is something like 'various artists'. 'album artist' tag is intended mostly for compilations. if stored 'album artist' tag is empty then its *displayed* value (everywhere except for tag editor) will be gotten from 'artist' tag.
One question about this album-artist:
I use this album-artist for sorting my music into "happy", "normal", "hard" and "silent". So i wrote this words into the album-artist to get fast to my "happy" songs for example. And many songs do not have an album-artist entry. So i want it to be empty (and not to be filled with the artist name).
Sadly MusicBee uses the "artist" value for "album artist" when it is empty. Can i disable this? I do not want to have any artists in the album-artist tag displayed, because this will destroy my sorting method i have.
