Might have something to do with Music publishing/money laundering.
Music publishing is basically designed to disguise the source of revenue. Who can say that Purple People eater did not get 700 k plays in Vanuatu yesterday?
If we examine the history of consolidation in music publishing we'll see how two companies which publish 99% of all music could handle these transactions and more sophisticated ones. We also find that the people involved come from bloodline families who have featured prominently in our research at QR.
