It's not even a throwback. That U2 album still shows up if I accidentally open Apple Music. I haaaaate it. I disliked U2 before any of this, but now I have absolutely sworn to never ever listen to any of their music.

Google did the same thing with Transformers 2 I think. It still shows up as Purchased for me even though I absolutely did not purchase that. Good way to ensure I never ever watch any Transformers movie!

There was a website to remove it completely from your library, it launched in 2014 and was up for many years, but is now gone.

These days you can delete the album from your library and set the Music app to not automatically download your purchases. If you want to go an extra mile, you can login to your iTunes account to view your purchases and hide it there too.
