Just to comment: I wish you could also "reset to playlists" or "reset to saved", and have it rebuild a profile from scratch based on existing playists (and/or saved media) and just the history of those songs in your profile. That way, you could just clean up any playlists they made (or things you wanted it to forget!) and rebuild, which saves you from having to start "completely fresh" unless you want to. (It would also flush out any listen history for non-saved media.)
