I'm sure anyone who has kids and online music will have faced the embarrassing situation of an inappropriate song coming up on radio or a playlist.  This can also be a problem in workplace listening and public spaces.  Why can't we have a toggle switch for all online music services with a default to clean songs only?  Spotify have been petitioned since 2012 for the ability to block explicit music and no action has yet been taken.  Google music has an option to block explicit songs in radio but could go further.  Amazon has no option (this is shocking with Echo devices now in many family households). Let's get a huge petition going that they can't ignore!
