That's question to the music authors. They probably decided to sell the licensing rights to an "evil" media company.
Here I stand on "right to burn" author's side. They can do whatever they want with their music, like putting a trillion dollar price on it, or selling it to an evil publisher. It's authors's nonprescribable right. If you don't like it -- feel free to write your own music.
That game makers should have probably make a modification to the game to replace original music with something else.
