To be honest, music often distracts me, but even distractions can be good sometimes. They get your mind off the issue at hand so you can work on things subconsciously. You might jump to a new issue and find the solution to the old one.
I listen to a large variety of music, but for programming, I normally listen to heavy metal and recently I have been listening to dubstep. It is my favorites of what I would normally listen to, though. I find it best to keep the playlist short, though. After hearing the same thing repeatedly, it becomes background noise and only pulls me out of focus periodically. Like I said, that can also be a good thing.
