[PROBLEM] Unable to use Airplay from Apple Music on Windows

[Mecworks]

Why do you think it's a moode "bug"?
We use stock shairport-sync latest release for AirPlay service.

Weather or not it's your bug or not is not the point.  It's a deficiency.  If you want, I'll call it a feature request.  Either way, it's not doing what a lot of Windows users want.  Redirecting by asking if it's actually a but avoids the actual issue here which is that you cannot play music from Windows Apple Music while other platforms can.
