My "fab 5"...in absolutely no order of pref....
50s on 5 (but, puh...leeze, cut back on the number of intrusions to the main format)
60s on 5 (concerns about playlist getting a bit tighter...as also seems to be the case with 50s on 5)
Air America (I'm politically independent, but get fed up with the dominance of right wingers on terrestial)
Escape (strictly for purposes of putting me to sleep. I'm dead serious!)
On the Rocks (now only available online...and presumably only in lower bandwidth once AOL drops XM)
I also like the news & sports stations, Luna, 40s, 70s, The classical channels, the country channels, Old Time Radio, and a few others. The problem...at least with the music channels...is the usually inferior audio qaulity from my two recievers and the streams xm's own website. Streaming via aol is much better, but that's going away May 1.
