I just discovered the blog of Bruce Warila. It has some great articles and helpful advice. Bruce writes about himself in his blog:
"Since 2003, I have been involved in strategic planning, product design and managerial roles pertaining to the development of digital products and services for the music industry. I am well versed in all facets of the music industry, music industry startups, music industry products and services, music promotion, music information retrieval science, and the obstacles and challenges that artists, record labels and rightsholders must overcome to be financially viable."
