Question:
I am a programmer who uses electronic music (not happy, no lyrics) to put me in the "zone" and concentrate at work. Is it permitted for me to continue listening to electronic music for this purpose on the omer?
Answer:
Music that is played in order to help a person do their job is not considered music for happiness and permitted to listen to while you are working.
Best wishes
