Great topic - And I am with Chris for one reason:
Publishing has never been easier than it is today.
The hard part of being an artist nowadays is not (as it used to be) getting the music recorded, printed, distributed, published.
Instead the hard part is getting an audience and attention on the internet. Therefore - once someone has the attention of a following on the web, they need to take ownership of all that implies, including the rights to streaming of their content.
Scarcity used to dictate the music industry. Now it is attention. What does the billboard top 40 even mean? Top 40 for who?
Artists should IMHO, work on building their own audience, and dictating their terms when people start knocking on their door for a share of the pie.
