I worked on this book for 11 years, and it’s hard not to see advertising as a kind of virus that’s everywhere. I tried really hard not to be critical of the people I was studying, because it was mostly people who just wanted to make a living as a musician. And who am I to say that you should starve as a musician instead of make a living as a musician? [laughs] But at the same time, advertising is so ubiquitous. And in the US, advertising exerts such a huge influence on what gets broadcast or what movies get made, that it’s pretty much impossible to make a distinction between advertising music and music, because the commercialism of our culture pervades everything we do.
