I don't get the Sex Pistols either.
Nobody should "get" fake punk.
Everyone should dig real punk though. Actually, no they shouldn't, not everyone should like great music, it's just too damn good for some people.
I don't like fusion, though I liked it as a young teenager when I thought complexity = quality. I do like jazz a lot though, just not the showy-off for the sake of it stuff. (I'm aware plenty people will say that just because someone is playing something difficult, technically or harmonically, they aren't necessarily showing off.)
