I have this problem too. I find it completely useless to have tags like genre=Post Rock Jazz Fusion" or whatever with basically one band in each genre.
The other thing I've never quite got right is how to deal with classical music and popular music with multiple pressings. A lot of the tagging structure seems oriented around popular music with just one pressing. But I have like 10 different recordings of The Planets and several versions of Red Hot Chili Pepper's Californication, for example.
