I discovered it this morning when I got in my car, and CH 2 was gone. When I got to work, I went to the unofficial XM Forums, and found out
that as of today, they've axed 7 or more channels, and not only changed the names of others, but completely changed some of the formats!
Lucy, my favorite, is now called 1st wave, still touted as classic alternative, but now playing The Police and Joe Jackson?!?! And now there's a DJ yammering away too, about nothing even remotely connected to the channel's format!

1st Wave of nausea is more like it.
People on the XM forums are furious, it was totally unannounced by XM except for a leaked copy of the new channel list that escaped on Friday. I'm not sure yet if I'll cancel, since the '40s channel and Bluesville are so far unscathed, and I don't have any terrestrial radio available that is listen-able.
Tom Petty's Buried Treasure S4 is premiering tomorrow as well, and unlike TTRH, there aren't any downloads out there that I know of.
Since my receiver's in my car, and my (internet) satellite connection at home doesn't allow for streaming audio, so being able to catch TTRH and Buried Treasure, between interruptions at work, all day long was wonderful.
Someone on the forums said he called to cancel, and they offered him a year's sub for $77 if he didn't cancel. Did they make you a similar offer?
XM treats their customers like dirt, not even giving them a hint that this was going to happen. All the time saying the merger wasn't going to change anything that they already were already offering.
