Brown jug, I agree with your Oak Grove assessment. The handicapper is sharp, but does share eccentricity with his father, a longtime writer in the sport ( I try to avoid Dad’s columns in Harness Racing Update).
As for between-race music, it, too, drives me nuts. Serves absolutely no purpose at all. Yes, there is a mute button, but at times, one gets distracted, and may miss a program change or the start of a race.
