I think the theory is that you need to distract a certain part of your brain if you want to get on with a task that requires a degree of concentration. Dance/trance works pretty well for this (for most people). After all music is just a way of tricking the brain into enjoying counting.

Once I tried listening to classical music, I found it very difficult to program to. I decided that the music was too complex and actually used the complex-task part of my brain (which I needed for programming). I also had a similar experience when I tried to play a language learning tape in the background while programming.

It's a fun experiment to run on yourself either way.

I find that whatever music I use for working out works best. I guess there's some link in my brain - the meditative state you get into when you exercise where it's just you, the pain and the music puts your brain into a highly focused state. I discovered that after a while of doing this, whenever I listen to my exercise playlist, it puts me into that same focused state regardless of whether I'm exercising... and I now use the same playlist for highly focused/fast pace programming. Of course it helps to maintain the link between that kind of music and focus if you regularly use it for exercise.

YMMV

If you're still interested, try solo stringed classical pieces while coding. Bach's solo cello suites are a good place to start.
