To add songs and playlists to your Library, you must use Cloud Music Library.

I keep getting this message on Music App on macOS: "To add songs and playlists to your Library, you must use Cloud Music Library."

I've seem to have done all my best to synced with out success, little did I knew how difficult this task can be, and no one could help me, I been living this inferno for many months and not even on Tech support knew what was happening. The last thing they told me to do was to install macOS clean, so I did, but not even that helped. If there is a soul out there that knows how to solve this before I get lost in oblivion for all eternity, please help, other wise... life has no meaning and it will be better to pack my things and go fly a kite, music is everything for me, can't go on like this no more.
