It couldn’t be deleted. It hung around like a dog turd smeared in the treads of your boot.
Everyone at Apple HQ had essentially the same reaction as you, “who cares if there’s another album in their library?” They learned that a whole lot of people cared, a lot.
I cared because I have never bought a single anything through iTunes. Not one; I find the entire “locked down music thing” utterly despicable. So my “library” was so clean that it never showed up in my iTunes app; the only thing I saw were the discs I ripped on my PC. Suddenly, at the very top of my Music library, was a single album that I did not ask for, want, or would ever listen to. It gave me a giant middle finger every time I opened iTunes.
So I stopped using iTunes. Completely. I host music on my own server (using Plex), and listen using the Plex Music app. It’s not convenient - Apple is actively hostile to apps that replace their apps; they don’t allow you to register a “replacement” app for Music or iTunes (or Maps or Messages or Calendar or …). So Siri is useless for music. But I’d rather rub two sticks together than use their iLighter when they treat me like this.
(And no, Android is far worse than Apple because it’s backed by Google, the world’s largest advertiser who is actively undermining its privacy at every turn.)
