If someone wanted to hide a playlist or station that was personal to them such as a playlist for a special moment in their life they could hide that playlist instead of having to keep a secret alt account. Additionally, if i set my profile to private, i should be able to share a link to a playlist with my family/friends and they could add that playlist to their collection but they can't view any of my music stats. it would be a HUGE help if this was added as a feature.
