Well I went to Best Buy last September and I bought XM Radio. It is wonderful! I could never go on a road trip now without it. I picked XM because it actually had more news channels on it. I *think* Sirius seemed to have more of a sports emphasis, which doesn't interest me. They charge a little less too I think - $10/mo vs $13. XM has a much larger subscriber base too - several million versus Sirius' 750,000.

And the music is great. For exmaple, they have 3 "gay" dance music channels. One is your mainstream dance dj channel, and then the other two are a little more relentless BPM / tweaked out themed. Then of course there is "Chrome," a sort of 70's disco channel.

There is a channel on XM Radio called Fred. It is a channel devoted to playing "progressive music" mostly from the 80s -- you will hear lots of Clash, and The Smiths, DM, The Cure. I listen to it often, as I hear music on there I haven't heard in years, and selections on albums I owned and sold ages ago. It freightens me.

They have a channel called "Cinemagic" which is a pretty good channel of movie scores. I find it to be a little "pop" --- I'd much rather listen to Raiders of the Lost Ark or North by Northwest then to the music from League of Extraordinary Gentlemen.... but it's made my presets.

They also have a channel called Vox, which is all choral music, and its very pretty.
