@Sakonosolo:
Even part 1 had a lot of music references. Dire, Straizo (Dire Straits), Tonpetty (Tom Petty), Tarkus (EL&P album), Bruford (King Crimson member), Speedwagon, among others. Off the top of my head there were less in part 2. Cars, Wham, AC/DC, and Santana (all bands) but there may be more. Most of the stands in part 3 weren't named after bands but quite a few characters were and part 4 and on is where every stand being a music reference started.
There were still quite a lot in part 2, but a bit harder to catch.
Some of them were mixes of artists names. Smokey Brown is Smokey Robinson and James Brown. Loggins and Messina are Kenny Loggins and Jim Messina. Pretty sure the rest of the named characters have some reference in them to a certain extent.
Also, the Red Stone of Aja is a song by Steely Dan.

What do they even give those kids in Jojo to eat anyway? I know no 12 year-old that looked like both Dio and Johnnnathan.
What's worse, Jojo's teens or Dr. Stone's
! Tsukasa's army of buff 15 years olds?
