Yeah last time I used Pandora, every station would inevitably turn into "freehunter's favorite songs". Rap station? Well Run-DMC did a cover of Walk This Way, and Linkin Park is kind of rap and Beastie Boys did a lot of rock songs, and now suddenly I'm getting a lot of rock in my rap list, and rock melds into pop pretty easy, and now suddenly my rap playlist has Katy Perry and Kesha.

And thumbs down is always way too harsh in any algorithm you'll find, because there's no way of telling the algorithm why you didn't like it. If I thumbs down Thunder by Imagine Dragons, how does it know I really do like Imagine Dragons and that album was good and the genre was good, I just don't like that one song? And if I thumbs down Good Riddance by Green Day how does the algorithm know I love Green Day and I like that style of music, but I just have a really negative emotional attachment to that song and I don't want to cry right now?

Context is super hard but super important. I listen to a lot of ambient music at work and now my Apple Music and Spotify suggestions are all ambient music, even though I don't listen to that genre for pleasure.

While I haven't used Pandora (it isn't available here), you seem to be describing my experience with Spotify's various playlists. With no personal context or ranking, the algorithms have nothing to go on except how many other people liked or repeated a song. Other people have awful taste, and seem to love to put songs on high rotation that I find mediocre.

And without decent playlists and music discovery, why would you pay a monthly subscription instead of once-off fees for music you like?

I wish the algo changes the preferences based on the time etc. S, if you can set "work hours," or label it that way, it will play the sort of the music you like during those hours, while something else for other times. You can have multiple "moods" set - one for commuting, one for partying, one for night time etc.
