The reason Courtney Love, Dave Grohl and Krist Novoselic is not happy about the use of Kurt Cobain for “Guitar Hero 5”, is not that they put him in the game without their permission. Courtney agreed to put Kurt in the game in the first place, she gave them permission. She gave them permission for Kurt to sing Nirvana songs for the game. She didn’t give them permission to use Kurt to sing songs by other artists.
This is why Courtney, Dave, and Krist are pissed off and on a warpath against Activision about it.
I totally agree with it. It’s totally embarrasing and sickening to have Kurt singing songs by other artists like Bon Jovi, Billy Idol, etc. I’m like, “What the hell is Activision thinking? The company are a bunch of fucking morons”. This is humiliating for Nirvana fans.
I am so glad not getting the game. I too am upset and dissapointed with Activision, and because of this, I will no longer by anymore future released Guitar Hero games.
I will still keep Guitar Hero III, Guitar Hero: Aerosmith and Guitar Hero: Metallica, of course, but I will no longer support Activision. They might ruin the upcoming Van Halen game as well.
This is so wrong having Kurt Cobain, singing songs by other artists, that is not Nirvana. So now you see why they are upset. I can’t blame ’em.
See the video below, this is terrible.

I guarantee this is all for publicity on Courtney Love’s part. She controls his estate, and I’m sure she was involved with the project every step of the way, as Activision has already stated she was. Classic example of a celebrity acting like they need to maintain their “rock and roll” cred, and further, she knows this will create more buzz around the game, translating to more sales, translating to more money in her purse. If for some reason she WASN’T involved all the way, then that’s her own fault for not paying attention to it.
Watch for there to be no actual lawsuit.
