This is absolutely fascinating, well worth doing. Takes 20 minutes and needs headphones. Ai and Emily did well (of course) being in the top 1/3rd for musical ability (beats, detecting mistuning and remembering tunes).

I'm in the bottom 1.4% with near zero ability to detect correct beat, zero ability to detect if someone is singing off-key, and poor memory of tunes.

But I listen to classical and older pop music all the time and love hi fidelity sound (I can detect distortion and poor balance easily) ... so there!
