It depends how serious you wish to take music. As a musician and songwriter I've worked in several band's. I can tell you one thing for sure, attitude is everything. I have fired musicians for having bad attitudes in the studio. A good business relationship requires a certain relationship involving respect and dedication. Having different approaches to how things are done can be great business wise being that you have different strengths and weaknesses. My singer is not good at organization but kills PR. I am good at the managing and organization. Together we work different but parallel But don't mix business and friendship. Hopefully this was a little informative.
