Are you feeling more positive about improvements in audio quality?

Amazon is the first big company to go high-res. Amazon has seen the light. They like disruptive things, and they've done a big favor to music. You might have to buy a few things. A digital-to-analog converter could be as cheap as 99 bucks. Plug it into your stereo system. Use wires. We've gone the wrong way on a lot of stuff because things are designed for digital. At least Amazon is leading. They are so far ahead of Apple and Spotify. Qobuz is OK. Tidal is OK but they screw with the sound. We made the sound, just play it back, thank you. As much as I love Jay Z, I think Tidal missed the boat technically and now they've been surpassed completely.

What advice do you have for aging fans who stopped listening to music years ago?

They may not be listening because they don't get from it what they used to. For their own souls, they should know it wasn't them. It's technology. At the same time we were getting older, the sound quality went down. It's been degrading over the last 35 years. Now they can set up a system and drive it with an Amazon app. It's something to do. How often do you have a chance to learn something new about something you love?

How likely is a Crosby, Stills, Nash & Young reunion considering David Crosby has burned so many bridges?

Crosby should write an introspective book: Why People Won't Talk to Me Anymore. He made a lot of great music for a long time. I don't know what happened with David. I got nothing to say. I love Stephen. I love Graham. If a reunion happens, it would be a surprise. I won't close the door on anything. I can hold a grudge with the best of them but only if there's a reason for it.

As the cofounder of Farm Aid, how do you view the state of farming in America?

I say tear the whole thing down and start over. We're damaging earth by the way we grow. Industrial agriculture is a scourge on the earth. They've displaced all these working people who loved the land and took care of it. The big agriculture companies only care about the bottom line. You have to work with nature. The thing is, it's reversible. We need world leaders with brains. No more chemical farming. Stop using GMO seeds. Why do seeds have to be owned by someone else? I say that seeds are owned by God.

Are you planning to work indefinitely?

I could never do a retirement tour. I'd feel like Cher. Don't retire unless you really aren't interested. I'm interested. It hurts a little to play now where it didn't before. I don't hear quite as well as I did before. My voice is not like it was before. Show me something that is like it was before. I feel good about the future. The idea is, do not stop moving.
