I would've posted this thread sooner, but was unsure of when and where to post it. I didn't know if I should post this in Toonami, since JoJo's Bizarre Adventure is currently a Toonami Anime, or to post this in Music because the series is highly music-oriented.
In the past, I already said at least a few times, that younger viewers would not necessarily catch all the music references in this franchise. If you are 30 years old or younger and only listen to a certain music genre or sub-genre, the references probably went over your head.
For example, did you already know that the main villain, Dio Brando is named after Ronnie James Dio? Some of us already knew this. However, if you are not a fan of Metal, never was exposed to or grew up listening to Dio over the last 3 decades, and happen to be much younger, chances are highly great, that you didn't catch the reference.
Anyway, here are 3 videos explaining the music references in JoJo's Bizarre Adventure for Phantom Blood, Battle Tendency, and Stardust Crusaders.
