I don't know a ton of the specifics for music, but I am not sure if I agree your statement is always true. A lot can go into producing and distributing music, and I don't think it is fair to say the artist should always make more than all the other people who work on making the music happen combined. It isn't just a 'company' making that money, it is all the people working behind the scenes, all the investment in equipment and things, etc. I would need a lot more info on cost breakdown before I say the blanket statement of "the artist should make more"
