Ok so I created a smart music list to download almost 6000 songs. Wasn’t are it would take up all my iPhone memory..had 235mb/256 left. So I went to settings and iPhone storage and removed all music. That should have been fine. Well now I’m seeing “system data” at 154 gigs. That’s a little high. Before this mess I have just over 200 gigs. Is it best to just erase all and start over?
