I have a similar problem where I play Disney music/movie music in the car when I drive my kid to school. Every time I have to go find "private mode" deep in the settings. Typically I just forget. I am primarily a discover weekly and release radar user, so it's definitely frustrating. They have basically done almost nothing positive for users in years in terms of UX. They tried to git rid of dislike, but brought it back because it ruins those suggestion playlists, when you can't hide awful songs.
