^ Oh ok.. I've never really seen any dvd's break that down
People make the business seem more complicated than it is and probably the most difficult thing to understand is the royalties like radio play, ringtones etc which is the money that comes in after the cd stops selling which the newer artists always forget about and end up getting screwed over.
The business is just like everything else... distributors, retailers and promotion. A point = 1% and the more clout you have, and the more demand for your product, the more points you SHOULD be getting
but yeah, don't know of any dvd's that explain this lol
