I clean in total silence. I don't like to be distracted by anything. I even shut off the ringer on the phone. Concentration is key to my way of thinking. If I'm distracted, I could screw up something. That could lead me down the road of disaster.
When I'm outdoors I prefer the (relative) silence. Indoors I usually have a ball game on (baseball or football, season depending). Either way I prefer not to have other folks present. The very ritual of breaking the guns down, cleaning & reassembling is my version of meditation.
