Apple Music has had some really impressive growth since it launched last June, so does that mean should Spotify be worried? Even though it’s still the undisputed king of music streaming, Apple Music is growing at a ridiculous pace, and many people are wondering if Spotify can keep up. Well wonder no more, because Spotify founder and CEO Daniel Ek tweeted on Monday that Spotify now has more than thirty million paying subscribers, meaning it’s added ten million in roughly the same amount of time it took Apple Music to add eleven million, so it’s definitely keeping up.
