XM vs Sirius vs FM
Had it not been for Hurricane Katrina, I'd be living in Chalmette listening to WTIX-FM. THE BEST oldies station on the planet. But since that's gone now, I have my Sirius radio. My stations are 70s, Elvis, Classic Vinyl, The Vault (classic album rock), Roadhouse (classic country), The (whatever the Christian station is), Siriusly Sinatra, Blue Collar Comedy and Laugh Break. And now after T-day, I have it set on Starlite 2 which is now Sirius Holiday.
If I'd do it over again, I'd get XM. Better fidelity, bigger playlists, more music stations than blah blah blah talk channels. XM started their Christmas music early. They have 2 of them Special Xmas (funny Christmas music) and their normal Christmas music.
