Hi all, I am having problems with playlists in my music, any playlists i create appear on other family members devices also and vice versa which surely shouldn't be how this works? I love my Rock music which isn't something my mother or father would want to listen to yet my playlists and albums i create or download show up on their devices. Am i doing something wrong for this to happen? Also something else strange happening is all the songs i had when i used iTunes Match are showing up still but greyed out and can't be played. why is this?
