Drum creativity is song creativity. And look, it's another Dave Grohl drumming performance.
We must also thank bassist Krist Novoselic, because he really comes through with a dark, moving line here. In the chorus especially, it lays the basis for and really sells Kurt Cobain's whining guitar stabs.
I think my favorite moment, other than the wonderful verse harmonies, is the ringing, ragged final note of the too-short guitar solo.
This song was supposed to imitate the form of "Smells Like Teen Spirit," which it kind of does. But for a song that's supposed to be a knock-off, I can't think of anything else that sounds like this thing.
