Google Play Music becomes the 15th Android app to hit one billion installs. This somewhat shows that the number of people activating Android devices continue to grow. Google Play Music now has an extensive list of features on it since it launched in 2011. It lets users store personal music collections online, buy individual albums to stream via All Access subscriptions, and have personalized radio stations. Of course, this many installs don’t translate to all these users actually on the service. But, as mentioned, it does show the growing number of users on Android.
