The rest of the numbers are actually fairly telling. The Label costs are actually where you can see what I'm talking about. I'm guessing that this is really probably less without the retail requirements.
Promotion probably becomes highly digital and the costs drop there also.
I'm generous, though, and I'll suggest that cost savings in marketing will convert into a record label's profit, the record label essentially taking on the role of promoter. A equals X plus Y plus Z. X is work. Y is play. Z is keep your mouth shut.
