Seriously, I don't think we NEED any of them, since Heart Shaped Box was in GH2, Welcome to the jungle is in GH3 and War Pigs was in GH2 as well.
We'll probably get the whole Nevermind album by Nirvana, so I think we have enough Nirvana. Personally I have enough of GnR and BS too, but I'm sure there still will be enough DLC by those bands.

In Bloom > Smells Like Teen Spirit

The other Nirvana songs aren't necessary (especially covers) and we already got HSB in GH2.

I don't like November Rain too much either, but the rest of the songs are pretty good.

no one should ever need any nirvana. you got one band right but unfortunately the right answer was "Black Sabbath - Career Spanning DLC"
