Yeah like i sayd before, it is impossible to sub genre a full round music album.

Of each genre i have right now there can be made several sub genres, but if i make those sub genres there will be more sub sub genres.

I am thinking about the simplest form of music, the several basic music styles.
Wikipedia is my main source of these genres i have right now.

I fully understand what your saying, but each genre i have have certain very close sub genres, if i create metal, i only have 1 sub genre in rock, that would look odd.
So i have to make more, since there are plenty more, but than soon i will find myself in a huge forum with all kinds of sub genres of music and make the entire forum more complicated than it already is (in it's simplest form)

I am going to stick with the basic of basic.
