What is up with Pandora?

Microsoft seriously feels that Pandora is so important for them as a platform? A service that has explicitly ignored them for 2 years. Now MS finally has a competitive product to Pandora. And what do they do? They pay a few millions to Pandora, for having them write an app (assuming that Pandora did it, because it may be on Microsoft's dime) and for the free subscription agreement. That's what the platform lacked? Spending those millions in a dozen different ways would probably be more beneficial. Nobody cares about Pandora on the Marketplace MS! You still get a 5 on ecosystem by reviewers!!!
