Nine Figures 2 is now available for release. Those of you who fondly remember it as the best way to get the current count of how many songs Apple has sold on the iTunes Music Store back when they were climbing to reach 100 million songs. Well, 9F has returned for the new 500 million song race, and has brought along a killer new feature that Apple’s doing – fast incrementing. Really fast. In fact, in theory, it can be as fast as you want (if you know your way around command-line).
