I've actually been on support chat with Spotify over this issue but apparently the "Home Mix" feature isn't fully functional or something like that.
Anyway, the my issue with the Home Mix is that it doesn't update often enough, you can't reset it, and you can't just delete it. I used to have on a Spotify family account with a sibling that apparently used to listen to a lot of pop country, and since the Home Mix is populated with selections of music that all users on a family account listen to, the playlist is mostly pop country. I have since removed myself from that Spotify family account and have obtained my own but the Home Mix hasn't changed and still is full of pop country and other artists I would never play. It actually quite frustrating. So it's pretty obvious that the playlist is **bleep** up from being populated from one Spotify Family account then not updating itself according to a new one.
As I stated before, it would be nice to be able to clear the playlist so that it'll generate from music currently played, or at least have the functionality to delete it so's not to have a playlist full of music that makes you cringe.
