Is it obligatory to leave a job where one can pray and wear the hijab, but where music is constantly present, or to continue in it until a better job becomes available?

The questioner is congratulated on her steadfastness, performance of prayer, and wearing of the hijab (definition). Listening to music is forbidden, as is remaining in a place where evil is being committed without denouncing it. If a woman needs to work and has no one to support her, she must seek permissible work. If she finds no work except in a shop where there is music, she must strive to advise those in charge to stop the music or lower its volume, or she can distract herself from it with private headphones. If none of this is possible, then it is a situation of necessity, and she should continue working until she finds permissible work.
