Let's accept the assumption that iTunes pricing doesn't obey the rule of lower price implying greater volume. For the theory to hold up, iTunes would have to represent a significant share of an artist's total revenues. Otherwise the artist wouldn't be bothered by a decrease in iTunes sales volumes.<p>But! As the importance of iTunes sales grows, an artist's incentive to keep a record label as distributor diminishes. Any artist can list themselves on iTunes - why would they share revenue with an evil record company if they don't need help with distribution and marketing?
