Right... that feature... Yeah I didn't implement that during the rework. There were just too many open questions and the PR back then was oversized enough.

But it seems spotify sends 6 tracks with the request. How many recommended songs were displayed to you?

We might be able to load the given tracks. The question then would become, how we resume after these are done playing? I would assume it continues playing, but from which context? Or do we just switch to autoplay?

That sounds about right. 6 songs showed in the recommended songs list for me.

As for the context, the behavior on the phone is that the 6 songs are considered "Playing from playlist" according to the header on top of the player. Once we've exhausted the 6 songs that where queued from the playlist's recommended songs, it continues playing with a new track that's not from the playlist or the recommended songs and the header on top of the player states that it's "Playing from recommended tracks" which I assume is autoplay.

I suppose if we just handle the tracks and then transition into autoplay that should be relatively simple to implement. There needs to be some adjustments to the current play request, but besides that it should be relatively simple.
