Host (what you are running librespot on):

• OS: Linux
• Platform: Debian Bookworm

This is my first usage of "DJ X". For me, librespot gave those same errors but then it did play the correct track. But only that track and then stopped, the "queue" is empty (there doesn't appear to be a queue available for DJ X). Maybe that's the same as you describe in your OP, isn't clear to me. I think it might be playing the fallback uri instead (which in my case was an actual track URI, rather than the DJX playlist again that you got).

This feature works quite differently from normal playlists. Notice that https://open.spotify.com/playlist/37i9dQZF1EYkqdzj48dyYq doesn't load. Someone interested would need to investigate what their Spotify client is doing to resolve this weird playlist.

It’s exactly the behavior I have.

Here’s how DJ X works:
DJ X talks for 5–10 seconds, then a playlist of 5 songs plays. After that, he talks again, and another playlist of 5 songs follows, and so on.

I don't have access to the feature so I can't help on this end. And I'm not even sure we can support this when the context we are getting, doesn't have any tracks.

Spotify Public API doesnt seems to provide any info about DJ X tracks... Digging HTTP requests from Android Spotify should help me to understand how it works.
