[Jojo's Bizarre Adventure] Has it ever been commented on in-universe that Stands tend to have music-based names?
gpt
It's possible that most, if not all, the characters haven't made the connection. Music is a vast field, with so many bands that nobody has heard of all of them. How many Jojo fans have listened to all of the bands and got the references without having to look up the bands, albums, and song names?

To make matters more complicated, the Jojo universe is littered with music references to such an extent that the references sometimes predate what they reference, making them non-references from the characters' POVs. Fore example, Joseph probably shrugs off the three 80s bands that share names with the Pillar Men as mere coincidence, as the Pillar Men predate them by decades - and Joseph is the closest to an avid music fan that we see in the series. And this happens not just with stands, but people's names, locations, organizations, and whatever could possibly have a name. For the characters, the "references" are so everyday that they might as well not be anything out of the ordinary.

And many of the references in modern times are kind of dated for the people that use them. How many young people in the early 2000s do you think would recognize Moody Blues or Stone Free? (A lot of fans don't even get that Jojo itself is a reference.) Add in the fact that most of the characters live in countries other than the US/UK, and you've got a lower chance that they are that well acquainted with western rock music.
