Yeah, I love Rude Jude and Lord Sear on Shade45 in the afternoon. They play some good music too, not just the newest stuff out, but stuff from the late 90's that seems to have been forgotten about on regular FM radio.
The best thing about Sirius (and probably XM too) is the variety of different types of music. Their talk stations are pretty good too.
And no, I don't own stock in Sirius.
