Pretty awesome, Alessandro. I was able to create a Tidal playlist from a rather obscure Russian band to test its limitations - the results were more than impressive given the genre (Post-Punk, Dark Wave) and artist exposure, which is very much non-mainstream - even within their own sub-genre.
From my understanding related artists’ recommendations are reliant on the size of the user base, and now AI, which is why I’ve found better recommendation results from Spotify (751 million) in comparison to Tidal (5 - 7.5 million), Quboz (250k- 500k), and Roon (100k - 150k) - guesstimates per Gemini AI.
Even then, your results were more focused under the “balanced” playlist creator than Spotify’s recommendations within an established playlist of the same artist.
Maybe I was lucky with that first search, but the results, integration with Tidal, and slick UI are impressive - wicked job there, sir.
