Why do you remove songs from Apple music?

There is no rhyme or reason why half of an album is removed and the other half stays. Why do you do this? I pay money for a service. I expect to log in and have the music I saved available every day. There isn't even a warning, you just change and restrict the songs I save without caring about the entire userbase. FOR ABSOLUTELY NO REASON, today I can't play a song I've been playing for months. I switched from Spotify to this, but Apple seems 100x worse. You remove songs at your own whim. Apple music is absolute trash. From discovery to availability. You're supposed to be industry leaders, yet you fall so far behind, my grandmother is asking where your last location was. Do. Better. Keep moving like this, and no one will use this deprecated service anymore. Like I said, I moved from Spotify, it won't take much to move to a completely different service again if the trash continues.
