"Jeannie Becomes a Mom" by Caroline Rose plays first every single time Spotify tries to generate radio for my Indie Mix playlist. This has been happening for months. You can click "Don't play this again", but since the contents of the *Mix playlists change every day, the don't play list is wiped every day.

I wish I could universally blacklist a song (at least for a couple of months), but that only works for entire artists. I've seen the exact same complaint for the exact same song on reddit, which makes me wonder if it has something to do with their program that lets artists jump ahead in the algorithm (https://newsroom.spotify.com/2020-11-02/amplifying-artist-in...).
