Digitally Imported radio (di.fm) is a great trance channel. I used to subscribe for $5/month to get their higher quality feed, which was worth it when I had good headphones. I spent a lot of hours in the library coding and doing math listening to di.fm. They have other great channels like "chillout" and "house" which are also good for coding. Chillout is, well, chiller and good for relaxed coding sessions and house is a bit more funky and less "poo tsh poo tsh poo tsh poo tsh" like trance can get (and can get annoying).

ASOT++ btw. I listen to it every week. You can d/l it on most torrent sites, which isn't even as illegal as d/ling other music. Its like taping the radio and giving it to your friend. And this radio doesn't have commercials. Plus trance style music lives on a different plane of business than the rest of the industry they way I see it - which is a whole different tangent I'll not go down.

I find trance excellent for coding. It's relaxing yet energizing, and not distracting.

ASOT, nice, I listen to that as well :-)
