This morning I updated my iPhone, selected to use iCloud music library (because Apple said I had to use it to use Apple Music), and everything was fine. Then I got home and updated iTunes. Now every song I've ever bought (about 50gb of music on my hard drive) is appearing on my phone. It doesn't appear that they're all downloaded to it, because the option to "make available offline" appears next to songs that I did not previously have on the phone, but I they're all showing in My Music, even though I have the setting to only show music stored on the phone turned on. Is anyone else seeing this? Is there any way to fix it?
