I don’t know how you can say with a straight face that smells like teen spirit isn’t one of the greatest modern rock songs. That riff is etched in music history at this point
1. Where Did You Sleep Last Night Unplugged
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.
