[MAC] Apple Music vs iTunes (offtopic)

[rant start]
Just a rant here

Why Apple in it's infinite wisdom has decided to retire iTunes for Apple Music.

On iTunes (on Windows) it was so easy to make a portable Library of your Music, and now I have I switched to Mac, i need to use Apple Music, their new app for managing Music Library.

But even a simple copy from the library inclu Music files from my NAS to an external SSD prevents a sync from my Phone to the new location as it keeps searching for the OLD NAS, even when changing Media Location. I managed to solve it, by exporting the library and importing it back into a Completely new library, but common Apple this is not portable anymore.

Why change a winning team? Beats me
