Metal detector ists ! Ah no, oops, you had it right, force of habit ;)
I'm not sure if the habit is because of the show or not, but I wanted to note for anyone who might be reading that "Detectorists" is a really charming British show that I highly recommend.
So either the elevator is on the same network, or they misconfigured the broadcast to all networks instead of the one needed. First one being much worse as it shows a failure to understand network segregation.
Why? It's highly likely they just don't care. Which is fine. It's an elevator speaker.

it's not the elevator it's, a speaker inside the elevator. nobody's hacking any elevators with this.

That's more of an annoyance than a safety issue though. This is definitely one of those YAGNI things where it's not worth worrying about until it becomes a recurring issue, which is highly unlikely.
Personally, even the remotest possibility of someone broadcasting "evacuate your rooms, there is a fire/active shooter in the building" seems worth spending a few hours protecting against.
Although I could be wrong!
Would have been more entertainig if he had broadcast his own UDP music. Perhaps the 8bits were some checksum to prevent such hackery?

What will the elevator speaker do if it received 2 music packets instead of 1?

Eh, the sound system on the elevator being hooked up to the guest and entertainment network isn't really a sin in my eyes.
As long as it's segregated that way. Someone was able to gain access to their Dr's office's network by accessing the wifi-enabled fish tank thermometer. I forget if the details of how exactly they accessed it, but it was an example of an Internet of Things device making a security hole in a network.
