Sure, Spotify has 100 million paid subscribers, and Apple Music has 60 million. But Amazon won’t be left in the dust. According to Financial Times, the number of people subscribing to Amazon Music Unlimited grew roughly 70 percent in the last year. As of April, Amazon had more than 32 million subscribers across its music services, including Unlimited and Prime Music. While Spotify leads the pack with the most subscribers, it’s growing at a slower rate, about 25 percent per year.
