Apple's streaming service now has 50 million users through a mix of paid subscriptions and free trials, CEO Tim Cook unveiled Tuesday.

Speaking to Bloomberg, Apple's CEO also said that his company is "very interested in the content business," and that "will be playing in a way that is consistent with our brand," without providing further details.

Apple is trying to differentiate its product from rival Spotify by offering original programming to its subscribers, including series Carpool Karaoke and Planet of the Apps. Apple is currently readying a large content push through its newly created original programming division, led by Sony TV veterans Zack Van Amburg and Jamie Erlicht.

In april, Apple said that music service has 40 million subscribers. Cook did not detail how many of the 50 million users are free trials.

Apple Music still sits behind competitor Spotify, which has 75 million paying customers.
