Ok, I just realized something about the issue with the multiple artists being scraped as 'A Perfect Circle'. All of these artists are part of a 4 cd classical box set that I have set up like this.
They are in a folder called 'Various Artists' with a sub folder under the name of each album.
The artist and album artist tags are both the name name of the composer.

When I originally ripped these cd's I had each artists tracks in a separate folder under their name along with there other cd's if they have any.
For example any Beethoven tracks would be in my Beethoven, Ludwig Van folder with a subfolder for the cd from the box set.
Some of the artists only exist in this box set for.

Thinking I may have to switch back to the original setup....
Actually it will serve another purpose as well... with the setup now each of the composers wont have individual folder art, artist.nfo etc.

For compilation albums Artist tag contains the track artist, whilst album artist tag would be "Various Artists".
On my file server I have a various artists folder I dump all my compilation albums in there.

There is a setting in XBMC for music where you can hide the display of compilation artists. So for example when you go in to the music artists area of the GUI you would then only see album artists. I always turn this setting on as I don't want to see random artists that might only ever appear on one track off one compilation album etc.

This means you can then consentrate on getting all the artwork right for just the album artists.
I also had to contribute a lot to theaudiodb.com site and add meta data and images for some of my artists that previously had none. So if they weren't on fanart.tv or on theaudiodb.com sites, I'd add them to theaudiodb.com as contributing on that site is easier and less strict.

Edit: Also once you have added your "missing" artist to theaudiodb.com site when you then reload that artist again in XBMC the new info and images for the artist will be correctly displayed.
Also when reloading an artist there should be an option for "manual" where you can manually edit / type in the artist name you are looking for, however chances are if the system didn't automatically find the correct artist you will need to contribute it.
