The company is willing to take huge steps to score deals, the tipsters say. It offered to spend millions of dollars on venue sponsorships, for example, and has talked about selling tickets on the secondary market, StubHub-style.

Live Nation, Ticketmaster's parent, has declined to comment. We've asked Amazon if it can comment.

As before, Amazon has plenty of incentives to offer tickets. Its sales elsewhere are built around up-front pricing, and it could become a major player if it lures fans tired of seeing one ticket price and getting another. Also, this could be yet another way to drive Prime subscriptions. If you knew you could get first dibs on concerts in addition to Prime's other perks, you might be more likely to sign up. At the same time, it's easy to see why Amazon wouldn't make many concessions on data. Whether or not it's concerned about customer privacy, its gigantic account database is one of its most valuable assets -- it likely doesn't want to do anything that undermines the value of that data.
