I don’t know, but I suspect it’s not as simple as you say. For example, look at the problems with theYoutube plugin that Google limited to xxx number of hits per day.
Edit: I think that Apple Music support would be stupendous, but I really think that it’s unlikely to happen soon (please someone, tell me I’m wrong ;)).
Since Apple Music doesn’t have a free tier (all users would be paying customers), I don’t really see a reason for Apple to throttle it, unlike Google with Youtube. For example, Apple Music is supported on Alexa devices.
Do you still have that “Apple music browsing” plugin somewhere?
From the wwdc 2018, “MusicKit on the web”:
“We’re also launching the MusicKit JS library. Makes it really easy to use both of those REST APIs in the browser, and it gives your users the ability to play back full songs from the Apple Music catalog and from the iCloud Music Library right in their browser.”
We would love to integrate Apple music, but so far we could not access any SDK that makes it possible… An SDK is the part we need to understand how to talk with a service and stream audio from it. Usually we receive directly from the service which allows us to access it
If/when integration for these big streaming apps are available (i.e. apple music, amazon, youtube), will they be exclusive to Volumio premium like Tidal and Qobuz integration?
very likely, because these kind of integrations require substantial development & testing effort and then there is also a certification process involved in some of the cases. All-in-all very time consuming and not always as easy as it looks.
