> Same with Netflix, in my experience they truly know what I will like to watch... Wow, I'd love to live in that world. Once Netflix abandoned their 5 star system their recommendations really tanked for me. It feels like it's recommending more based on outrage & "engagement" than enjoyment for me. Meanwhile MovieLens [1] consistently guesses what I would rate a movie within +/- half a star, I think I'm using their Warrior recommendation algorithm. The tagging features on MovieLens help - apparently I most enjoy "visually appealing surreal mysteries". But I absolutely agree about Spotify. Spotify seems like its actually learning from my Liked tracks, curated playlists and behaviour, and picks up on when my tastes shift to wildly different genres for a while.
