Just switched to Android (samsung s6) from being a longtime i0s user, so I realize I'm clueless. I've backed up some of my music (including text tone length tracks) onto google play. But to add ringtones in android, it wants to take them from the "music" app. I don't get how to add my music to the default "music" app. It's driving me nuts because all the generic ringtones are so very lame. Love everything else about the phone but can't seem to figure this out no matter what I google. Heeeeeelp!
