That's right whitebelly, I had that option checked previously. It caused a massive number of one track artists to appear in the artists menu. Thanks for the suggestion jjd-uk, but I'm pretty sure that's not going to do what I want.

I've just noticed that all of my Triple J albums (Triple J is an Australian radio station) still appear where I want them under Triple J in the artists menu. None of the tracks have artist = Triple J but they still appear exactly where I want them. It looks like "Various" and "Various Artists" (anything starting with "Various"?) get shunted off to the hidden Compilations section. My Ahk-Toong Bay-Bi U2 tribute album comment earlier was a red herring. On closer inspection I found that album had "Various Artists" in its tags too. I had meant to change them to U2 but I never got around to it.

I'll see what happens if change the album artist tags to "Compilation Albums".
