I mean, it’s probably just up to whoever first started doing it. They chose that song, so it’s that song. Other songs may have also worked.
But there is one thing that I think gave Rick Astley an advantage over specific other groups like A-ha. And that’s his name. If you look up the history of Rickrolling on Wikipedia, it says it replaced a meme called “duckrolling”, which was used the same way as Rickrolling, but it was just a picture of a duck with wheels. So the advantage is that “Rick” is his name and it’s an easy drop-in replacement for the word “duck”.
There’s other artists who have names that would work. Who knows? In another universe, they might have “Beckrolling” or something.
Edit: I was just reading farther into the Wikipedia article, and the guy who made the first Rickroll said he chose it because it came out in his birth year of 1987.













Before humans invented barns, barn owls were actually called “bar nowls”. They were a type of nowl that lived in bars. It wasn’t until barns were invented that they changed species and changed into owls.
