Why some of my old music file cannot play after I upgrade to iCloud music?
I turned on the iCloud music and Apple Music. And I understand part of the effects after turned on the iCloud music, like the radio playlist is attaching iCloud. But how come some of my old music (mp3) unable to play on my phone? Does that mean I need to purchase them????? or ask iTunes Match to save me???
iPhone 6 Plus, iOS 8.4
