That's not really the idea that I'm repulsed by. I'm repulsed by the bizarre notion that music format eras should mention a political leader for any reason. It's like saying records really started declining after Nixon (or whenever/whoever is most appropriate, I'm not sure of the timing). It isn't necessarily incorrect, it's just categorically wrong to bring that information into the same thought.
