You make a good point about the possibility of mining all this data, but I'm not sure I want to give it away. We (well, some of us), go to lengths to maintain separate online personas. Why do I care if Facebook knows what my most-played songs are? I can get that info from iTunes, etc.
They're going to need a strong pull (killer app, privacy controls, whatever) to get my data.
So instead of sharing data with your friends, family and a corporation you just want to share it with a corporation? Someone already has your online data the only difference is who that someone is. That someone can still choose to sell your data on to anyone who will buy it in most countries.
