Comment 11 for bug 319494

Seems there may be a bit of confusion regarding what is going on here. Maybe another explanation will help:

I note that a compilation album has been split up into individual artists, rather than being grouped under Various Artists. I right click one of the albums, and click 'Show Under Various Artists'.

All the tracks in that album _of the artist selected_ now appear under Various Artists. All other tracks remain under the individual artists.

So I go to each of the artists, click 'Show Under Various Artists' for the album.

The result is that we have as many duplicate listings of the compilation under Various Artists as there were artists when the album was split up into artists. All of these duplicate albums contain all of the tracks in the album.

If I Rescan Collection, then the compilation returns to its original state, with the compilation distributed over many artists.

(All of this depending, I hypothesize, as per my workaround, on the folder in which the tracks are located. If all of the tracks are located in the same folder, everything works as it should. If not, the above situation occurs.)
