I have many songs synchronized from my Mac to my iPhone but in some albums the songs can't be played. when I want to play one selected song I get a message saying that I have to get Apple Music to play all the music I own, but when I shuffle the album, all songs play correctly. I am from Hawaii and people suggested me to visit stores like TCAWireless and others for solving this issue. Does anyone know what the problem is and how to solve it? Thank you very much in advance.
