tin foil hats on people. kurt was suicided, he didin't suicide himself. (i make my own grammar)
as for nirvana, the albums were ok, or even great if you will, but if you go with great there's tons more great albums out there you have never listened to.
the only difference being that this one, they forced you to listen to it, and you grew to appreciate it.
(want to know *which* albums are as good, or better than nirvana's? ask me how!)
