That's a somewhat of a maths/logic fail.
When Spotify started about how many active users did they have in thier ecosystem?
When Apple Music started out how many active users in thier ecosystem'??
One could argue that 15 million active subscribers for apple, given thier huge user base is a massive fail.
Spotify had to work thier way to 30m subscribers from nothing.
Apple has 1 BILLION active devices...they gave all its users free access to Apple Music for 3 months, and even after all that, just 15 million subscribed.... Maybe time to reflect that something is wrong with the service.
Apple Music should have blown away Spotify in the first year had they got it right.
