It seems like every recommendation algorithm gets into a state that is broken eventually. For the music streaming services, I find they end up in one of two states, either it shows me the exact same artists and songs over and over again even if I skip their songs constantly, or I'll play a song once out of curiosity or accident and it decided that that genre is all I am interested in listening to for the next month. Is it really that hard to map artists
I got so frustrated with Tidal recently that I finally sat down and finally setup a media player on Linux to play my locally saved music (most of which is from What.cd).
I still find that, even after all these years, Pandora's recommendation engine still seems to be the best. I can tune into stations that I created, jeez, 15+ years ago, and it might play one or two tracks that I know, but it quickly diverges into new tracks that are still within the "flavor" of the station, but I've never heard of.
