As someone who grew up in the 80s and 90s, I also really wish we'd gotten the explosion of almost completely sample-based music we were starting to see with bands like the Beastie Boys, the KLF, and Pop Will Eat Itself. The Biz Markie sampling case basically shitcanned an entire nascent subgenre.

Which sampled the guitar melody from Lou Reed's "Walk On The Wild Side."

Which sampled this part of "The Sorcerer's Apprentice" by Paul Dukas. (Okay, not quite but it's easy to guess the inspiration.)
Without samples and sequencing being the primary production technique, suddenly real instrumentation and organic musicality became the thing. Hip hop started building on covered riffs and musical passages more than straight up samples (I’m guessing the licensing was easier).
That also gave us Check Your Head from Beasties, as the follow up to the pioneer sample-laden album Paul’s Boutique, where they famously played their own instruments again and became even more popular. The Native Tongues scene also gave us Prince Paul/Dr. Octagon, which gave us Deltron 3030 and Dan the Automator, which gave us Gorillaz, which…
There really was a lot I suspect would’ve gone quite differently without that court case.
