The "mega bucks" often roll in because the artist is saying something that people want to hear. I have listened to and admired many singer songwriters, I have also listened and admired many folk musicians. I don't see these things as being opposed to each other. There are talented musicians in all fields of music. It seems to me that a lot of people in the so called "folk" world see success as an automatic indication of having no talent...when this is clearly not the case. Many very talented musicians have been hugely successful and have made "mega bucks".
