I know a couple of recording artists. One a punk rocker from England and the other a Christian Music folk guitarist from South Dakota. They don't want me spreading their names around because of NDA. They both say the same thing:
They only make money on concerts, very little on media sales.
Both of them support filesharing stuff like Napster and the like because it gets there music out there. They don't care whether music is out there by radio, filesharing, or by people buying CDs and tapes. The publicity is what gets tickets to concerts sold, and that's how they make their $. Butts in the seats!
