Long time Spotify user here. Recently I was doing a search for classical music playlists and came across one that was extremely familiar.
Turns out this playlist (named "Relaxing classical piano music") says it was "Made for" me with 100 likes and 50 songs in it. I never made it, and it isn't findable on my "Made for you" part of Spotify. It isn't a genre mix (no "Mix" in the playlist name), nor an artist, daily, or decade mix.
What feature is this? I did a search for "picked just for you" and I found a ton of other playlists with 50 songs in it, each customized for me based on my previous likes. Is this a hidden feature? Is there a better way to find it except for searching for "picked just for you"?
Attached is a screenshot of some of my search results.
