Actually, that’s borderline doable. Browsing by artists, the artists could be dummied up easily enough:
select distinct artists from songs where compilation=0 union select "Various Artists"
That one would be easy to fix up.
Then when you select “Various Artists”, the soundbridge does two queries… one for all albums where artist = “Various Artists”, and one for all songs where artist=”Various Artists”
That would take some uglier fixups. It would be doable, though. It might in fact be worth doing. I might play with that.
