Jay-Z used some lyrics from Nirvana's Smells Like Teen Spirit.  Courtney Love said it was OK.

Speaking to the Huffington Post, Kurt Cobain's widow says that Jay-Z used the song, "without asking.  Which is kind of nervy but the business side has been taken care of so it's fine."

Love admits that her daughter will not be happy when she learns about it, . "I'm letting Jay-Z use lyrics - Francis would freak [if she knew this.] Jay-Z's huge and we're friends. I mean we're not besties or anything."

In 2006, Love sold a chunk of her stake in Nirvana's catalog.  Surviving Nirvana members, Dave Grohl and Krist Novoselic, also own stakes in the catalog.

In the past, Grohl and Love have both said that they guard Nirvana's catalog.  Love has claimed that, "nobody else will bother protecting him [Cobain]."

Dave Grohl has said, "The band stood for something; we took pride in our integrity and in our band."  But, he has not commented on Jay-Z using Smells Like Teen Spirit.
