Architects, interior designers, even engineers, have to “sell out” on their original designs in order to satisfy the customer. We all “sell out” in one way or another in order to make a living. Does a kid that wants to be a professional skateboarder sell out when he gets a job at McDonald’s?
My only complaint about an artist selling out is that I miss the style of music they were making and usually don’t care as much for the main stream version of their music.
