For the past 1 1/2 years I have listened and remain amazed at this "free lunch". But I am no parasite! You can click on their page to contribute to listener-supported commercial free radio.
This works for nearly any internet connection you might have: 56k, DSL, Broadband, Wireless etc as they offer a selection of streaming speeds to accomodate. The bigger your pipe, the higher the fidelity.
