Not sure if it's coincidental, I was offered two weeks back to try Apple Music again with one free month. I tried out when it was first launch and never subscribe to it. So my trial must have helped out with a +1 in the number.

Which is more than I can say about quite a few subscription services (looking at you, lynda.com).
