Leonard Lopate had Moby and Walt Mossberg on his show to talk about the music business and how people consume music. There isn't anything new, but the show nicely captures what is going on.

Over the years I've done a few things with digital music and have two learnings
1. Music companies exist to exploit the end user and the musician
2. In the end people don't care about audio "quality"
Both of these came as complete surprises, although they seem obvious now.
