Hmm songmeanings.com has following opinion about the nirvana song:
Kurt said it himself that this song has no meaning and that it's a bunch of random poetry lines thrown together to a kick ass motherfucking melody. This is one of my favorite Nirvana songs.
Yeah, I'm going mainly by the ironic title to be honest - it always feels to me like Cobain's snarky response to studio pressure to make another Nevermind. I've not looked into closely though, I have to admit.
