Anyone listen to radio stations over the internet? The advantage I have with DSL at work is I can listen to my choice of music, and some of them have no or few commercials. This is the two I use the most now:
http://www.alldanzradio.com/
http://www.beethoven.com/
The alldanzradio has a very wide selection of music styles (not neccesarily dance music)
I used to listen to Virgin records site, but they started making a big push for subscription service.
Beethoven.com is great when I want good relaxing music to think by. I don't always like rock when I have to concentrate on something. Too annoying.
