Windows Media Center has Sirius XM in it but this is not a free service. There are several radio options available on the net though. Radiozilla is a good piece of software for internet radio and you can hear stations from all over the world. I like dance music a lot, it peps me up so as for an online station, and there are a lot of them, I listen to GIRL (Gay Internet Radio Live) It is really upbeat and although I still seem to be online too much, it gets me going round the house when I just gotta get some stuff done. (Like now but eh, here I am) Just about all radio stations allow you to listen in on their websites, at least all that i have seen. Anyway, enjoy your listening choice!
