Here is the referenced July paper [1]. Spotify has a very cool feature called Community [2] where users can talk about what they want Spotify to do. The most upvoted ideas are things like "change my username" or "filter explicit songs." My personal wishlist is a "don't play this song again" button [3] and native Homepod support [4]. The point is that users aren't asking for Spotify to interpret their emotional state,…
I've argued that recommendation system for music are near useless for years because they don't group music together by what I actually want to hear together, and that it needs to be more careful about interpreting my actions because what goes together varies by mood and purpose.
E.g. you can't just take genre,or artist, because the music I want before bed need to be slow, soothing and familiar. Transitions between tracks also need to be much less abrupt than other times of day.
Other times I want something new and surprising.
Or loud and upbeat.
Until they convince me they can do that they're not getting my money.
