[Poll] Background Music, Yay or Nay?

As I'm sure some of you know, music and music composition have always been a close second behind art for me. Like many (if not most) people, I've always enjoyed having some kind of music playing in the background while I work - usually a movie or game soundtrack or something. That is until recently. Now I find that I work much better in complete silence, the reason being that it allows me to focus better and lose track of time much more easily. So here's a simple question for all of you!

Do you prefer to have background music or noise while you work, and if yes, what kind?

P.S. - these poll thingies won't have any kind of time limit, so comment your answers whenever!
