According to the Financial Times, Apple has passed 10 million paying subscribers for Apple Music. Apple Music launched in June 2015 with a three month free trial. Since the launch, Apple announced it has 6.5 million paying subscribers in October. In November, Apple launched Apple Music on Android which no doubt attracted a significant chunk of additional new users.
Crossing ten million is a significant symbolic milestone, as it now means Apple Music is half as large as Spotify’s paid userbase.
