iTunes Giveaway Estimates
One neat thing about this chart, is that it shows sales are already spiking in relative proximity to each of the magic numbers. We suspect people are watching the various iTMS counters and logging on to purchase a track as each of the 100,000 song milestones approaches. The odds of correctly calculating when to purchase a song using a counter are pretty damn bad. Todd's estimates make them significantly better, as you can get a to-the-minute forecast as to when to make your purchase.
