Question:
How should compilations albums be treated ?
It would be nice to have the album come up as a Various Artists album (eg. for a soundtrack) but when playing or searching, be able to display/search for the actual artist as well. This one seems a little more complicated and perhaps a general problem with tags.

I already have the problem of multiple songs from one soundtrack appearing as different albums by different artists at the moment.

Edit: I think it shows up "Various Artists" automatically if there are multiple artists with the same "Album Name". Be careful with multiple "Greatest Hits" albums, and rename them as "Greatest Hits of <artist>" where artist is the name of the artist.
