Personally I can't listen to music and revise my lessons with concentration in same time but I can see some of my collegues revise with earphones so it depend to the person .There are many Articles worldwide, that you can find on Google and Bing that state that listening to music while studying or working can drastically help with concentration. A lot of businesses and schools are allowing listening to the radio/music to their employees or students. Let's debate, does it help with concentration and make us more productive in the work or school place?
