If Nirvana had remained a small, underground punk rock band, Kurt Cobain would still be alive. And he'd probably be living in Seattle, getting kind of fat and balding, be relatively happy and producing records for other people.

One of the central flaws in the state of contemporary music is that the major record companies have failed to incorporate that simple fact into their business plans. They've come into an industry that's based on idiosyncratic artists and tried to erase every idiosyncratic aspect out of it.

Intellectually, human beings and animals may be different, but it's pretty obvious that animals have a rich emotional life and that they feel joy and pain. It's easy to forget the connection between a hamburger and the cow it came from. But I forced myself to acknowledge the fact that every time I ate a hamburger, a cow had ceased to breathe

My goal with everything that I do is to present things in a way that I would want to see if I was in the audience or buying the record.

The term 'renaissance man' is always bandied about. I don't think that applies to me. You think about Leonardo da Vinci, and he was a painter and a physicist and an architect, and that is a true renaissance man.

I found it incredibly disheartening that in the late '90s, suddenly pop culture became even more misogynistic and more homophobic, and so I criticized Eminem for having lyrics that were egregiously homophobic and egregiously misogynistic.

I don't think there's anything wrong with not knowing how to play an instrument, but the rise of the non-musical producer has done away with musicianship and focused attention purely on the song's hook.
