Hi
Some up to date research on the music industry. I think its Open Access.
Scheckter, Jonathan (2006) A holistic approach to consumption analysis in the popular music market. Masters thesis, Rhodes University.

http://eprints.ru.ac.za/216/01/scheckter-thesis.pdfIt has some interesting insight to the SA music industry. I can't cut and paste coz i'll be infringing copyright but its got interviews with people from Gallo, 5Fm - etc etc all of it.
Their experience and views on what makes and breaks the whole industry.
If you cannot view it, just let me know.
Its long but it gives a global overview, with a separate SA section.
