I think, and as this post suggests, it's much more the case that "Kurt Cobain had very good instincts for someone completely untutored" which is a different thing altogether.
I am very clear though, that "genius" and "intelligence" are unrelated but sometimes coincident.
I'm remembering a scene in Hampton Hawes's autobiography where a well known piano teacher was telling him his students were starting to ask how to play like Hampton. He tells him he wants to give him lessons to help his technique, which he thinks will help his natural talent even more, but Hampton finds it boring and never goes back. The teacher framed Hampton's check he used to pay for the lesson and put it on his wall. All that's to say having great ears can bring you a long way.
But yeah, feel, instinct, and having good ears can carry you a long way especially for solo artists. I'm still glad I can read music and wouldn't trade that for (almost) anything, though.
But also... what's John Lee Hooker's secret of the guitar??? Don't hold out on us!
But the gist of that method actually sounds a lot like how my music teacher approaches things, he won't let you move on in your improvisations on a new tune until you can get a feeling from playing just half and whole notes on the changes. His teacher was Lennie Tristano so he's very driven by developing that ear instinct.

2. Frances Farmer Will Have Her Revenge On Seattle (or, interchangeably, "Rape Me", though the "blanket of ash" line gets me every time with Frances Farmer).
3. Lithium
4. Heart Shaped Box
5. Dumb (unplugged).
It's not fair to make the #1 song a cover, but that performance merits it.

I think this was the statement he/she was disagreeing with. No doubt a genius, but when you phrase it like that it's more than genius.
When I hear people call Cobain a genius I feel the way I do when I'm hear someone say they've never seen The Wire. Listen to Surfer Rosa and Rid of Me!
None of this is to say Nevermind and In Utero aren't good; they're very, very good, I listen to them all the time 30 years later. But like, I still listen to Soundgarden every once in awhile too. They're not geniuses!
I think of Kurt Cobain like an accidental Elvis Presley. Perfect for the moment, and (unlike Elvis) mostly organically grown, but with very clear antecedents.
I cannot point to strong antecedents of Pixies, Sonic Youth, Throwing Muses, PJ Harvey, Cocteau Twins, Bauhaus, Einstürzende Neubauten, The Slits, Bongwater, Kate Bush, The Cure, etc. In a couple of these cases, I suspect my own ignorance. In others, I could (and might) argue all night! :)
But I cannot assemble a case for not recognizing David Bowie as a (musical|performance) genius. I don't even enjoy his recordings very much, but he was artistically sui generis and enormously influential.
Influence might not be a requirement of genius (I'm not sure), but surely a novel creativity is at the root of it?
Sonic Youth was the Velvets and The Fall; I found a list of setlists from '70s CBGB and made a playlist, and you can hear Sonic Youth all over it.
Throwing Muses (a favorite of mine) a little harder to pinpoint, feels to me like the product of a scene more than a direct evolution of clear antecedents, rather than an act like Dinosaur Jr. was a perversion of Neil Young. A good contrast to Nirvana.
PJ Harvey is the Pixies antecedents plus Patti Smith. People say Beefheart; I don't know Beefheart well enough to say and have a deep suspicion of people who bring up Beefheart.
Kate Bush is prog rock.
Einsturzende is Can (or like a violent response to Can).
The Cure is radio-friendly post-punk; their early stuff, which is the only stuff that comes close to holding up, is basically Wire.
But Sonic Youth also brought something new, more than most bands do. I've listened, as professional obligation, to the entire catalog of Velvet Underground, The Fall, New York Dolls, Iggy Pop. The Fall were the most inventive but Sonic Youth still exceeded them. I recognize that these are the giants upon whose shoulders so many other artists stand, though.
As with The Cure, there are (at least) two Sonic Youths. I see The Top and Daydream Nation as the final recordings of their respective original incarnations.
Interesting that you hear Throwing Muses as a product of a scene. I'd agree for the later records (post-House Tornado), but there was definitely no contemporary scene that the first few records fit into.
I thought about including Lush in my previous list, but did not because, although they had a unique sound, they are a clear extension of the scene they emerged from. Again thinking of the first few releases (EPs) primarily -- after 1993 or so all Brit pop sounds alike for several years.
Re: Kate Bush -- aside from the Fairlight (as successor to Moog) synth, and concept albums, I don't hear much prog rock in there. I think I may prefer to remain ignorant here!
I also left out Siouxsie & The Banshees (again, ~1980-~1990), which was an inexcusable oversight!
For Halloween, I duct-taped a banana to a tee-shirt, intending to go as Comedian[1], which had been in the news recently. My manager, when seeing me dressed this way immediately asked "Oh, are you The Velvet Underground and Nico? I love that album!" I countered with "Did you start a band?" and he said "Yes! How did you know?"
There's no shame in that!
