From an interview with the Guardian:
I’ve come through vinyl, tape cassettes, CDs, digital downloads…all along, the constant was that a song is required. The delivery system isn’t important. For me, I’d love people to be listening to the music in the most perfect way, so they can experience exactly what we made in the studio. But then it’s the difference between looking at a painting in a gallery and looking at a postcard of it—there’s still something good about that postcard.
Show them the postcard, and some of them will want to see the paintinng.
