iTunes app total downloads to overtake songs this year

Last week I posted the iTunes download rate graph that showed how Apps are being downloaded much more rapidly than songs and revealed an inflection point in the song rate.

Based on the recent updates to iTMS and iTAS on Sept. 1, the following graph shows the cumulative units of songs and apps downloaded indexed to the same starting date.

As can be seen, the App store has reached the same total downloads in 2.2 years as the iTMS reached after five years. The two curves are likely to be the same height (around 13 billion each) before the year is over.
