Another thing to consider is that this map is almost certainly going to change in the next few weeks. Apple probably hasn’t been specific about Apple Music countries because it likely hasn’t finished closing all the deals it must wrap up to put its service into place. So when you look at our data, bear in mind that some “blue” countries will become greens in the coming days and weeks. This is just where they’re at right now based on our investigation.
So how close is Apple Music to that 100-nation mark? As of this writing — and according to our data — it’s about two-thirds of the way there with 66 countries. That leaves another 52 that could get the service (i.e. those with access to iTunes but no “Apple Music” heading), so it has plenty of room to expand. Obviously, Apple wants to hit all 52 of those places, which would give it a total reach of 117 countries. And that would be a lot of people listening to Beats 1 radio and asking Siri to play the top hits of 1972.
So maybe there's gonna be more countries at the launch with it that just got their contracts done the past week with Apple Music (which makes sense since they did announce they'd pay and lots of labels changed their mind about the service directly after), or they're gonna get those countries soon, or the website could just straight out be wrong about a few.
