I absolutely love to connect to Shoutcast streaming music servers while I am at work. They are free, good quality and you always here new stuff. One of the sites I have really become fond of is Soma FM.

Soma FM specializes in a wide variety of electronic music; ambient to progressive, if there is a genre you prefer, you can find a suitable channel here. The great thing is all their channels are commercial free, so let tune in and give them a listen.
