MAngband

I found a website a month ago that's been serving me very well... http://www.finetune.com (no affiliation whatsoever) lets you make playlists from their huge catalog and listen to them for free. It's streaming audio, so I'd recommend cable or DSL to use the site with MAngband.

Hm, might as well post what I often listen to while diving. I use SomaFM alot (both at work, and for gaming) - I tend to not listen to overly distracting music when I dive (I play with extreme paranoia), and Soma's multple channels of groovy downbeat stuff is poifect.

I prefer my own cd's/mp3's, though sometimes a little noisy...
Good to get into the right epic battle mode.

Pandora.com is worth trying. I find it actually does a rather good job of putting together lists of things I'll like based on info I feed it.
