I would certainly agree, but then again... Who T* F* edited it? I have to say, I did not see this issue before I "tried" Apple Music... and I say tried because even with a free trial subscription, the service was abysmal and the most difficult to navigate resource I had ever see (I may as well have been navigating through Unix with command line). And I have thousands and thousands of songs that I LEGALLY purchased, but now that I am travelling in Europe, I cannot modify or add playlists to my iPad. So, the basis of your complaint is totally understood. After all, for songs I purchased via iTunes, and those uploaded from my own CDs, should be available to me to transfer to the iPad or iPhone that I OWN and have registered as authorized devices.
The bottom line is that Apple needs to get its act together and stop implementing "solutions" to problems that never existed. After all, this is not material that I am purchasing individual use licenses for and subsequently trying to use for Public Performances, which negates the issue of International Copyright laws being at play. The company has gone from a tech eco-system that worked seamlessly together, to one of a thousand hiccups and hindrances to law abiding customers. In full honesty, what this feels like is a backdoor attempt, by Apple, to force people into its Music and TV subscription services.
