Spotify’s singular focus on music sees it adding subscribers faster than the iPhone company with a streaming app on the side. Spotify has added 20 million paid subscribers in less than a year, while it’s taken Apple Music more than a year and a half to make that progress. Spotify now has 60 million subscribers, compared to Apple Music’s 27 million (as of June).Spotify’s ability to accelerate its growth rate despite competition from arguably the world’s most powerful company is a testament to the product and community it’s built.Apple Music offers three-month free trials, comes pre-installed on iPhones and pays big bucks for exclusive early access to top albums. Those advantages might help Apple Music win fans of particular artists, plus mainstream listeners finally switching over from MP3s. Yet Spotify remains the go-to streaming service for music lovers.
