This isn't to say that Spotify is squeezing out the competition. Apple Music took half a year to reach 10 million subscribers, for example, while upstarts like Tidal are carving out some space for themselves. It instead suggests that there's plenty of room to grow in the streaming music market as a whole, and that exclusives (or holes in artists' catalogs) aren't doing much to affect growth. It may take a long while before these companies have to poach you from another service to get your business.

We have 30 million @Spotify subscribers, but none of them are in Cuba ... yet. So cool to see Cuba opening up! https://t.co/nZa67f0l8U — Daniel Ek (@eldsjal) March 21, 2016
