This is not the first time that Apple Music's foray into the Android platform has been heard of. In September, Apple reportedly sent invites for a beta testing of the service.
According to Variety, Apple officially launched the music service at the end of June, and at that time made promises that the Android version would launch this fall.
Apple Music is the second app that Apple has officially released for Android. “Move to iOS,” the first Apple-made app for Android, was a tool designed to move data from Android devices to iOS devices.
Additionally, Apple has been distributing iTunes to Windows-run PCs and laptops, which shows their drive to make their services available to competing platforms.
Slashgear adds that while screenshots can be faked, it's best to keep in mind that Apple is really interested in spreading Apple Music to as many users as possible. The subscription-based music streaming service was originally available for the iPhone, iPad, iPod touch, Apple TV, and OS X users; but now with a cross-platform jump, Apple will probably reach a lot more than they originally can.
There's even a family plan that allows up to six people to share a single subscription. With mixed-OS usage possible, Apple will do a lot better than compared to just offering the same plan to iOS-only devices.
