I realized that there are some additional problems:

1. SqlAlbum::setCompilation
when setting an album as a compilation it does not invalidate it.
when setting an album as no compilation it does not invalidate all
albums where tracks are getting moved to.

2. SqlTrack::setAlbum( const QString &newAlbum )
Does not check if the old album is empty and could be removed. This also
leaks image cache.

Also I am pretty sure that I don't want to do a full rescan.
Is there some way around this?

BR,
Ralf
