Incesticide 

Only the best Nirvana studio album. It beats the shit outta Nevermind by a long shot. Try comparing Aneurysm to Come As You Are or Stain to Breed. There is absolutely no comparison because Aneurysm and Breed are more superior to any song in Nevermind.

Unpopular opinion, but Incesticide is the best Nirvana studio album
