is because it was in Jojo’s Bizarre Adventure.

It it (was?) a classic rock radio staple though that’s true. I’ve Seen All Good People as well. Yes could have probably gotten in without the 80s era by that metric. But that kinda illustrates what i was saying in that you need hits even though it should be obvious that hits do not define a rock artist and are not the goal nor purpose of many artists and subgenres of rock music.
Velvet Underground didnt have any hits and they got in, that’s a counter-example. but the Hall was pretty different back when they got in, and members solo careers had hits and commercial success to larger degrees. How many other hall inductees from the 60s-onward (the early rock artists are kind of a different beast entirely) are there that had few to no hits and minimal commecial success? Zappa maybe (he did have the one hit, but it was hardly a smash or anything).
