So I got the google music play streaming service on my google nexus 7 as well as my phone but everytime I add music to my library or add songs to playlist it takes up data space on my tablet, is this suppose to do this? I don't have any albums downloaded to listen to offline at the moment but last time I checked the app was taking up 40 mbs data, this might not seem like a big deal but it would be if I wanted to make lots of playlists
