I see what you mean now. Although "don't like music" is not the same as "aren't into music". This goes back to the definition of what "real" music is. I'm fairly certain suburban moms (one of the suggested demographics in the article) will know quite a lot about radio-friendly music through their kids. In that sense they are an ideal demographic. I also don't see a problem with testing the hooks of songs against the market before making a substantial effort in promoting those songs -- that's common sense.
