I see lots of people freaking out about this... but I'm glad it happened. Maybe I'm nothing more than a wishful thinker, but I imagine that since there's some business-minded guy now involved with the Nirvana catolouge, that means we'll be getting more Nirvana material. To me, everything else is secondary to the prospect of getting new official Nirvana material. There's oodles of stuff yet to be released. There are lots of things we know for a fact could be released (Fecal Matter and earlier demos, Unplugged DVD, Reading '92 DVD, Old Age boombox & home, Radio KAOS acoustic show, instrumentals from final session) and there's tons of stuff that probably exists (1994 home demos including group Do Re Mi, early '90s home recordings, songs like Everybody Knows I'm New Wave, unreleased sessions such as the outtake song from In Utero called Lulaby).
Plus Teen Spirit in a commecrial would be funny. It's like when that silly car used Bargain in their commercial... I'm like "WTF, I refuse to stand naked, stoned, or stabbed for some stupid car."
