Jeffster - you are good at this. You should be a DJ and analyze people then play their music.
Actually, I was a DJ in high school, and I tried for several years to get a radio career going, but it became tough once I became a father, I couldn't offer to relocate for a job, so my options became slim. I haven't given up on the dream of working in radio again, though. I've told my ESTP co-worker that we need our own talk show, because we have lots of great conversations where we take opposites sides of issues but keep it friendly and don't resort to name-calling. But maybe your idea of a "songs by type" show is a good one too, I'm going to try my hand at doing the other temperaments here pretty soon.
