On yeah. As to your question on a what's on site for Sirius. There is
such a beast. Actually, there is even PC software that  I *think* is
self-voicing. Check out
http://www.givemesatelliteradio.com

You'll find what you're looking for there: a list of Sirius channels
and what's playing.

I'd love to see something like this for XM. I'm sure there is, but I
haven't looked for it.
