Unknown Artist vs Various Artists
I am using iTunes 11.0.4 (4) and I'm mystified by its organisational behaviour:
Take two separate albums, both ripped from original CD, both compilations containing tracks from various artists. The compilation option is selected, so their files are both in .../iTunes Media/Music/Compilations/ Neither has an Album Artist set, yet when I go into the Artists view in iTunes one appears under the Compilations 'artist' and the other is not there. If I select 'All Artists' I can scroll down the list of albums by artist and I eventually find the missing one under "Various Artists", however when I select "Various Artists" in the artist list only albums with that written explicitly in the Album Artist appear.
Just to finally seal my confusion: if I try to sync the albums to an iOs device by selecting them manually in the Music tab, one appears as "Various Artists - album name" and the other as "Unknown Artist - album name".
I appreciate that I can probably solve the problem once and for all by setting the Album Artist for all mixed compilations to "Various Artists", but is this the right way to do it [and - more importantly - will it work]?
