Both iTunes Store music and iOS App Store apps are being downloaded at an increasing rate. Apps are just increasing faster.
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.
I'm downloading far more apps than music, what about you?
