Most streaming platforms generate personalized playlists automatically, but I'm curious about the underlying factors they consider. Do they rely mainly on listening history, genre tagging, or collaborative filtering from other users? How much weight is given to explicit user feedback like likes or skips versus implicit signals such as playback duration? Also, are there any privacy concerns with the data they collect to fine‑tune these recommendations? Would love to hear your thoughts on how these algorithms generally work.
How do algorithmic playlists on major streaming services decide which tracks to add?

I’ve noticed that after I kept looping my new reggaetón chord progressions, the playlist started tossing in more Latin beats, which seemed to be driven mostly by my listening history and the songs I skipped versus the ones I let play through; the few “likes” I gave only gave a tiny bump. It looks like the service also pulls in tracks that users with a similar habit profile enjoy, so collaborative filtering is definitely part of the mix, and while they gather a lot of playback data to fine‑tune suggestions, it’s usually anonymized to address privacy concerns.
