Nirvana's almost in The Beatles territory for me, in that I respect their place in the history of rock music more than I actually like the music itself. HOWEVER, this song is a fucking jam.
In case it's not clear by now, I'm a sucker for simplicity, crescendos and jarring chord changes, and "You Know You're Right" has all three.
Second time through, it's tentative, almost like it's putting a foot out onto a plank to make sure it'll take the full weight of what's to come without breaking.
Then we get the chorus, which has that Em-C-D chord structure from the verses, only when you do it at this volume, that C major doesn't just slide into line like it did with the verses. It grabs you by the wrist, twists your arm behind your back and says "You're coming with us, you snot-nosed sonofabitch" and tosses you into the back of the paddywagon without reading you your rights.
Then we do it all again, only louder.
It's like they wrote and played the first verse, second verse and chorus and then, instead of writing a third and fourth verse, said, "You know what? That was a really fun minute and a half. I could stand to back for seconds."
And it works, because that was a fun minute and a half, and it definitely doesn't get old the second time through. And after that, you've pretty much got your song. Just gotta let Kurt Cobain groan a little more and then we're done. What an elegant bit of minimalism this is.
