I agree with both of you. I wasn't trying to be an a**hole or anything. Like I said in my post I love Nirvana and they were and still are a great band to listen to. Cobain was a big influence on a lot of people. I accredit him as more of a songwriter than a guitar player though. Just like you said... "he wrote good songs". Since I posted in here and haven't given my opinion on my top five I might as well... here they are in no particular order:

1.Jimi Hendrix (most influencial)
2.Joe Satriani (started the virtuoso movement)
3.Slash (brought the blues to hard rock)
4.Mark Tremonti (Most overlooked guitar player in recent years. PS, I hate Creed... the guy can shred)
5.Jimmy Page (How many classic riffs has he come up with?)

Honorable Mention:
Kirk Hammett, Joe Perry, Stevie Ray Vaughan, Eric Clapton, Steve Vai, Jeff Beck, Kieth Richards, Randy Rhoads, Zakk Wylde, Mike Mcready,... the list could go on
