If you're like me, there are times when you need some ambient music to keep the right brain happy when you're doing a lot of left brain intensive work like debugging, researching a problem, or cranking out code. In light of this, I thought I'd share one of my favorite internet radio sites that helps keep me going even during those inevitable late nights that plague us developer-types, http://www.di.fm/.
This site operates just like a radio station only it has a variety of music your wouldn't typically find on the airwaves, minus annoying DJs, and has minimal commercial interruption.
To use the site, be sure to scroll down the page to where you see the Radio Channels section. At that point, you'll start to see all the channels that they have to offer. Once you've found the type of music you want to listen to, click on either the 24k, 32k, or 96k button and it'll start streaming audio to your default player. Naturally, the higher value, the better the signal quality at the expense of more bandwidth usage.
My recommendations are Trance and Chillout, but there are plenty of options for you guys to choose from. If you're at work, just be sure the IT guys are cool with you sucking up some of there precious bandwidth...
