If you're on high speed and install a connection to a good sound system from your computer, you can receive some fantastic stations including 5 channel surround sound. XM and Sirius are, of course, the most highly marketed but I like Radio Free Virgin.
www.radiofreevirgin.com One subscription for XM or Sirius, of course, which is now being built into most surround receivers leaves you the option of receiving the signal on your sound system, on you computer or in your car. Pioneer receivers have both built in Sirius and XM receivers so there's nothing to do but subscribe.
