Is it good to listen to music whilst you work?

I have started doing it. Mostly everyone else in my team does it. But is it a good idea? Listening to music while you work is relaxing, however does it help concentration. I, myself, feel better whilst listening to music as i work. Luckily the good thing is everyone uses there headphones to ensure no-one else has to endure their taste of music. What a great idea! Somehow i feel more motivated sitting at work listening to music, and i seem to do the same amount of work. What a great job i have!!
