It's about the journey, not the destination. But are you seriously suggesting he change it to a clickbait URL?
The story is the journey, and there is no story without suspense. The URL is the dust jacket- some people are going to see the URL even before the title. No one said anything about clickbait. Any URL without the spoiler is better.
I'm suggesting he change it to Hotel_UDP.html from Hotel_Music.html so it does not spoil that it's music.
