Sensor Tower:

Sensor Tower Store Intelligence estimates show that 40 million Android users globally have now installed the Apple Music app from Google Play, and we anticipate that the current quarter will be the service’s best yet for new users on the platform.

And:

New users of the app in 4Q18 were up 43 percent over 1Q18, and we project that 1Q19 installs will total 3.8 million for a year-over-year increase of 65 percent.

That’s solid growth. Another sign Apple’s shift to services is working.
