Sirius only has one jazz channel? Granted, it's been years since I had it, but they used to have, like, a big band station, a fusion station, a smooth jazz station, stuff like that. Enough that hwen on sucked, there were other options. "Turning the dial", like the old days, that's what car radio is all about, imo. That and ball games and crazyass preachers. Today they call it "channel surfing", although I've yet to get two girls for every boy.
On Sirius, when I had it, he only thing I ever could listen to at any length was the OTR stations, do they still have that/those?
