Thanks for your input.
In settings of Spotify app, you can choose some settings, like some privacy settings.
List by list you can also hide them from others. Only folks with link can then view lists.
If someone know your username, folk can always reach your profile. There's no complite block option for everyone else.
Hope this helps.
This club is like a hot spot, come on DJ drop that. We party on an airplane high in the sky, so everybody come to California. We're gonna have the perfect time of our lives.
