If you started your three-month trial the day Apple Music debuted June 30, your free period would’ve just ended as October began. But according to Apple Chief Executive Tim Cook, 6.5 million users have stuck around and maintained paid subscriptions.

“It’s going really well,” Cook said at the WSJD Live conference Monday. “We are now over 6.5 million paid users and 8.3 million people in the trial. Over 15 million people are using Apple Music.”

In early August, Apple senior vice president Eddy Cue reported that the music service secured 11 million trial members.

Apple set a goal of 100 million users before launching the service, which would surpass competitor Spotify’s 20 million paid subscriptions. However, Spotify offers users a free option for streaming music, while all of Apple Music’s entry-level access begins at $9.99/month, which gets you the full library, expert recommendations, and unlimited skips on Apple Music’s radio stations.

The service has been successful at garnering exclusive content since its inception, such as Dr. Dre’s Compton and Taylor Swift’s discography, acquired after a public battle between Apple and the pop star. Apple Music also hosted a music festival in London last month — formerly Apple’s iTunes Festival — with headliners including One Direction, Pharrell Williams, and Florence + The Machine. Apple Music users were able to steam live sets for free during the fest’s 10-day duration.
