> The exact same logic you used can be applied to music: once you've listened to the album once, you know how it will go, so what's the point of listening again?

Most music doesn't have the same kind of narrative and strong plot that stories like novels and movies do, this is a massive difference. And even if it does, it doesn't usually take a half hour or more to do such a change. That's a pretty big difference about the types of art.
