I really just like breaking down the barriers, whether it means doing an album with Linkin Park, an album with R. Kelly, or playing at the Brandenburg Gate with Bono.

That's why this generation is the least racist generation ever. You see it all the time. Go to any club. People are intermingling, hanging out, having fun, enjoying the same music. Hip-hop is not just in the Bronx anymore. It's worldwide. Everywhere you go, people are listening to hip-hop and partying together. Hip-hop has done that.

[T]he truth is that drug addicts have a disease. It only takes a short time in the streets to realize that out-of-control addiction is a medical problem, not a form of recreational or criminal behavior. And the more society treats drug addiction as a crime, the more money drug dealers will make "relieving" the suffering of the addicts.

For me, being with Obama or having dinner with Bill Clinton... It's crazy. It's mind-blowing, because where I come from is just another world. We were just ignored by politicians, by America in general.

One of the reasons inequality gets so deep in this country is that everyone wants to be rich. That's the American ideal. Poor people don't like talking about poverty because even though they might live in the projects surrounded by other poor people and have, like, ten dollars in the bank, they don't like to think of themselves as poor.

By the time I got to record my first album, I was 26, I didn't need pen or paper - my memory had been trained just to listen to a song, think of the words, and lay them to tape.

People really feel like music is free, but will pay $6 for water. You can drink water free out of the tap and it's good water. But they're okay paying for it. It's just the mindset right now.
