> Your reference to prompting is pretty disgusting since you try to shift the blame to the user.

I'm shifting 'blame' to Spotify, rather than the user or the AI model - although blame is probably a pretty strong word anyway for what is probably just supposed to be a fun DJ feature.

> All the prompts were crystal clear.

We don't know what the prompt is, because the FULL prompt will be a combination of the base prompt plus the user prompt. It's trivial to show that a modern model with a minimal base prompt will return correctly (as per my original post), so IMO there is probably something in the base prompt which is encouraging the model to return differently.

I wanted to clarify the first two points, but i'll not respond to the rest of your comment as it's a bit overly-emotive (calling what I say disgusting, rambling about the downfall of society as a whole etc).
