"Two Question's did this band change the way rock music was going in the 90s and was Kurt Cobain murdered?"

Somewhat, and yes. He was on enough drugs that I don't see how it would've been physically possible to kill himself. Love's own FATHER said once that he wouldn't be surprised if she killed him. Creepy.

"Better question: would they be as well known if Cobain was still alive?"

I've never understood why everything thinks that Nirvana is so overrated and that they would be nothing if Kurt hadn't killed himself. I had liked Nirvana for quite a while before I knew he killed himself. :P Besides that, it just doesn't work that way. Would the beatles still be well known if John hadn't been killed? Of course! It ONLY causes waves in the music industry/populace if the band is already popular. How many people outside of metal-lovers know who Dimebag Darrel is? How about that he died recently? Nirvana was already bigger than that when Kurt died.

"Most of the teens who claim to like them today are just saying that to be cool. I'm 22 (almost 23), and I was just old enough for them to be part of "my generation"."

Was? Why the hell do you have to like the music right when it comes out to have an opinion? That's just silly. Music is music, it doesn't matter when you listen to or like it. I didn't like Nirvana until about 5 years ago.

I think Nirvana deserves their fame. they're hardly hailed as the best band ever or anything, just very good. I think they were very good. Lyrically, melodically, technically. They were just very good. They were great at their heavy grungey sound, but also showed they had a softer side with songs like Polly and their unplugged album (which is excellent, I should mention!).

Just because they didn't invent grunge doesn't mean they didn't change rock, at least somewhat. I don't think saying "they brough the sound mainstream" and "they didn't change rock" make sense. They were part of a turn in music where heavier stuff was being brought mainstream.

People are always so completely critical of Nirvana. It seems like the new elitist "cool" thing to do, nevermind teens liking Nirvana.
