Seems like spotify and apple music both do the same thing here. the js api creates an iframe to their "embedded player" which is just their full player without a ui which will respond to rpc commands from the page.

Would be nice if paying users could access actual streams, although that would probably violate the drm or something.

Spotify DRM _has_ been cracked before (extraction 320kbps Vorbis streams without recompression), but for obvious reasons there are no ready-made public PoC's.

Doesn't librespot count?

Possibly. I haven't looked into it though.

Yeah Spotify doesn't give you an api for stream either, probably related to drm, i wonder how Qobuz(https://github.com/Qobuz/api-documentation/blob/master/endpo...) does this without DRM issues?

What makes you think Qobuz relies on Spotify ?

What do you mean by actual streams?

The audio stream. This will likely never ever be supported by Spotify/Apple because of DRM reasons.

Yes, the raw AAC / OGG content would naturally break DRM. Spotify, however, has a ton of libraries that allow for you to write your own clients, which honestly allows for an "audio stream" for most purposes if you are able to run an OS. You can write a very simple CLI app that plays Spotify music for example, and Spotify's libraries will handle the DRM.

"Audio stream" to burn to a CD or a tape cassette? Yeah, that's not gonna be supported.

Surely you could redirect the audio once it's been unencrypted by Spotify though? It has to be presented to your systems audio drivers in an unencrypted state eventually. I guess the downside is that you'd have to rip songs at 1x speed.

I wonder if you could spoof the system time provided to Spotify too and have it "play" the music faster than real time.

Libspotify gave you PCM. It's since been deprecated but old app keys still work just fine.

Their current SDKs are only for iOS and android. They do also have a Web player but the DRM for that requires playback through a Web browser i.e. You cannot write a simple CLI app that plays Spotify music.

Spotify is supported by some 3rd party DJing apps which would need access to the PCM stream (pacemaker and I think edjing). However they probably have some kind of secret licencing deal/API access.
