I was never a Nirvana fan but you can really feel the pain in this song which I think makes it good art. That and the MTv Unplugged version of “The Man Who Sold The World” is one of the few covers I like better than the original.
Nirvana wasn’t my favorite either, but I have to love Kurt just for being an enemy to Axl Rose, and what is now kind of a legendary tale about refusing to open for Guns n Roses.
