Frustrating. Lack of feature parity accorss platforms for an app supporting a subscription service is not acceptable, imo. We're all paying the same monthly fee, yet users of some platforms routinely get features before others. Plenty of software companies manage cross-platform, simultaneous, feature-identical releases, even when those platforms are wildly different (tripple A games developers, for example), so why do some mobile developers continue to find it so difficult? Release should be simultaneous for all paying customers, regardless of their platform of choice, and feature-identical (hardware permitting).
I am an Android user as well and I feel your frustration. However, the simplest reason why you'll see many apps being introduced to iOS products before you see them on Android is because of demographics and simplicity. While you're correct that there are more Android devices, Apple holds the greatest market share of any device manufacturer. That said, when developers are writing code for apps, it's simpler to do it for iOS because they only have a small handful of screen sizes to deal with (4th and 5th generation iPod & iPhone, iPad Mini and iPad). Plus, with some small exceptions, everyone who owns an Apple device has the latest version of the OS. It's far easier for app developers to write code for only one OS.
As I understand it, the newest Android OS, Kit Kat 4.4, is going to help tremendously. Almost every Android device will be able to operate Kit Kat. This includes devices with as little as 512 MB of RAM (those would be the original 4G devices that came out about 3 years ago, some people still have those).
While Kit Kat will help close this app roll out gap, Apple will still have a leg up since they only have about 4 screen size choices to deal with. Let's put it this way, Samsung devices... alone, have more than 4 screen sizes. This is the double edged sword Android users have to deal with when it comes to having more freedom of choice, customization and development over iOS.
That's weird. I could have sworn that the original announcement included the words "Spotify Connect will roll out to Spotify Premium subscribers on iPhone, iPad and home audio systems over the coming months, with Android and desktop updates to follow."
