Of course, if you are someone like Ani Difranco, who publishes her own CDs, you make about $15 (how much are CDs in USA? This is an estimate conversion from Aus, in which she would make about 27 out of 30 dollars for a CD), though she has to pay for promotion and everything.
The money that doesn't go to her goes to the record store, obviously.
