Just got back from the dentist. Background music everywhere. Those guys do
precision work and they have to concentrate. Just another data point.

I do ultrasonic wire bonding under a microscope, with 0.001 inch diameter
wire, onto pads that are maybe 100 microns square. I *always* have
music playing when I'm doing this.

I think it's a right brain/left brain thing. You need to occupy the
part of the brain you're not using when the other side is busy.
Music does that IMO.
