Uh... I donI do not listen to music when I work. Why? Because often the customer is IN the home as I work, and listening to headphones would be a message to them that I am not really thinking about what I do. Same with cell phone calls: I do not take them while working. Our customers DO watch us and DO judge us on our behavior. Never doubt that.
If NO ONE is home, I might listen to rock, or classical music. But to be honest, I take my work quite seriously, and want and need to focus on the job at hand. Thus, I have NEVER listened to music while I work professionally.
