These numbers were obtained by HITS Daily Double who claimed to have been given the information from anonymous sources. Naturally these figures have yet to be confirmed by Apple, but apparently these are statistics that have been shared internally by Apple with content owners, presumably to show them how Apple Music is growing.
That being said this does seem to be in line with Tim Cook’s statements during an earnings call where he said that millions and millions have signed up for the 3-month trial. However this doesn’t come as a surprise since unlike other streaming services that needs to be downloaded, Apple Music is integrated into iOS.
This means that it won’t take users much to activate it and have it count towards a subscription. The more important question here is what the numbers will be once that 3-month trial comes to an end. So far there have been some praises for Apple Music, but at the same time there have been just as many criticisms leveled at it.
