>They feel like silly experimental music and occasionally you'll get something amazing or just sloppy trash or something so bad it's good.
That's... surprising? "So bad it's ____" isn't a set of words I'd ever use to describe that era of Sabbath.
It is definitely experimental, but metal music was fundamentally cutting edge at the time, solidifying in the mid-late 70s.

Blasting Paranoid or Master of Reality when going down the highway feels amazing. Killer fucking albums.
I think a lot about the Dio albums, and I'm just like, "they ain't bad, but they don't really sound like Sabbath either".

>I wonder what all the rock kids and metal nerds will do when their beloved idols all pass away. It seems like all they listen to are old bands.
Nothing, usually.
Once everyone is gone, they will have already found the full set of music they will listen to until they too die, lol.
