if you don't read billboard magazine, i highly recommend you start. I started reading it a few weeks ago and ive really learned a lot. The people that write, for the most part know what they are talking about in terms of the music industry, music marketing, music management, and bands that are going to do well. I have a subscription to billboard.biz, that gives you the magazine aswell, and it has a whole bunch of really interesting really valuable content.
but yeah, every week, pick up billboard, so you can know what you are talking about.. especially when you say you want to work in the music industry.
