Back to topic... you do know the record labels do all the actual work that song writters, musicians don't have to deal with, right?
They pay for the marketting, the publicity, the news/tv/internet/radio adds, they arrange everything for them in order to stay in the good side of their fans, yata yata yata, they also pay for most of the needs that musicians/artists have (Which btw, is not cheap at all, they are some mood swinging pricks who like anything shiny and expensive), and yata yata yata... forever and ever... again and again...
