It's kind of strange to say - because I think I know what you mean and I agree with you to an extent -but I've found that organ music reveals the weakness in lp more than other genres. Sustained notes in the deep bass are the easiest way for me to hear the speed variabiliy in a turntable. Good 'tables are stable enough to sound mostly "spot on" speedwise to me...except on the deepest sustained organ tones. Anyone else notice this?
