I tried to search for a song I found to be quite cool, Rotoscoping by PTRD. I got two matches, one "Discover Weekly Archive" made by Skiley.net on behalf of NomadicDaggy (you, the creator of this post and service). The second one was a "On Repeat"-playlist! Here, I realized that it's possible to look at other people's "On Repeat"-playlists, even though they are styled by the Spotify app to look like it's your own.

It's kind of weird that I only found this song in your playlists, and not in one of my playlists which also contains this song. For example: https://open.spotify.com/playlist/0IntLgAqI2EysEvqwiivXQ?si=...

Anyway, I'm checking out your "On Repeat" playlist, however it might be better if your personally generated playlists are excluded? I'm not sure.

Really cool service!
