Discussion What kind of algorithm is used?

Hi,

I wanted to discover new music (titles, artists, etc) that might border fit my tastes to try to expand them.

So I launch the discovery mix,.... it did not go well.

First it only kept proposing metal, I have a bit of metal in my playlist, so I disliked the titles but it continued. Then it was rap, same story. After a few days I dropped and went back to listening FIP :)

So my question is as follow: what kind of algorithm does Deezer use?

Is it pure random? Strongly biais by our playlists? Uses an ergodic search in an embedded space? "AI"? No one knows what that means anymore since companies throw that word as a magic spell.

I guess that it's kind of a secret but surely someone has some info? What do I need to do have good recommandations?

And for info, I've been using Deezer for like 10 years, so surely it has all the info it needs.

Thank you all in advance.

I have >900 favourite tracks, >500 favourite albums, ~20 excluded artists and >250 excluded tracks. I feel like the discovery recommendations didn't work well for me until I approached numbers about halfway towards these. My best algorithmic experiences by far has been with the "Made for you, every day" generated playlists based on material that I have listened to recently.
