On June 21, Courtney Love revealed that she had given Jay-Z permission to use Nirvana's lyrics to "Smells Like Teen Spirit" on his upcoming album 'Magna Carta Holy Grail' (July 4, Roc Nation). This got us thinking that it's been a while since we listened to any Nirvana, and it's probably the same for you. So we made a mix of their greatest hits, because they have a kickass catalog, and there's no better way to celebrate the weekend than with a little headbanging.
